What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
(a)
To find all possible values of ab, we can use the identity:
a⁴ + b⁴ = (a² + b²)² - 2a²b²
Substituting the given values, we have:
16 = (a² + b²)² - 2a²b²
We also know that a + b=4, which means that b = 4 - a.
Substituting this into the equation above, we have:
16 = (a² + (4-a)²)² - 2a²(4-a)²
Simplifying, we get:
16 = (2a² - 8a + 16)² - 32a² + 64a³ - 32a⁴
Expanding, we get:
16 = 4a⁴ - 64a³ + 288a² - 512a + 272
Rearranging and factoring, we get:
4a⁴ - 64a³ + 288a² - 512a + 256 = 0
Dividing by 4, we get:
a⁴ - 16a³ + 72a² - 128a + 64 = 0
This is a quartic equation, which can be factored as:
(a-2)⁴ = 0
Therefore, the only possible value of a is 2, which means that the only possible value of b is 2 as well.
So, ab = 2 x 2 = 4
(b)
We know that a + b = 4, and since a = 2, we have b = 4 - a = 2
Therefore, the only possible value of a + b is 4
(c)
From part (b), we know that the only possible value of a + b is 4. From part (a), we know that the only possible values of a and b are both equal to 2.
Therefore, the only possible solution is a = 2 and b = 2

parallelogram and b is the length of the adjacent side.
(a) Solve the formula for a.
(b) Find the length of one side of a parallelogram whose perimeter is 100 cm and length of the other side is 30 cm.
We are aware that P = 2(a + b) units is the perimeter of a parallelogram.Consequently, the parallelogram's sides are 50 cm, 25 cm, 50 cm, and 25 cm.
Find the length of parallelogram ?We are aware that P = 2(a + b) units is the perimeter of a parallelogram.Adding up all four sides will reveal a parallelogram's perimeter.An area of a circle of radius r is known as r2 in geometry.
The circumference-to-diameter ratio, which is always the same and is roughly equivalent to 3.14159 in this context, is denoted by the Greek letter.
Let side a and the side next to it in the parallelogram be a and b, respectively.
The parallelogram's perimeter is equal to 2(a+b)=150, where a+b=75.
Since an is 25 cm taller than b, a=b+25.
By changing it in equation 1, b+25+b=75 2b=50 b=25 is obtained.
a+b=75\sa=75=25\sa=50
Consequently, the parallelogram's sides are 50 cm, 25 cm, 50 cm, and 25 cm.

At the movie theater, the total value of tickets sold was $2,647.50. Adult tickets sold for $10 each and senior/child tickets sold for $7.50 each. The number of senior/child tickets sold was 27 less than twice the number of adult tickets sold. How many senior/child tickets and how many adult tickets were sold
Answer:
To solve this problem, we will use the following steps:
Step 1: Let's assume that the number of adult tickets sold is x and the number of senior/child tickets sold is y
Step 2: We know that the number of senior/child tickets sold was 27 less than twice the number of adult tickets sold, so we can write the equation: y = 2x - 27
Step 3: We also know that the total value of tickets sold was $2,647.50. Since adult tickets sold for $10 each and senior/child tickets sold for $7.50 each, we can write the equation: 10x + 7.5y = 2,647.50
Step 4: Now we have two equations with two unknowns, we can substitute one equation into another to find the value of x and y.
y = 2x - 27
10x + 7.5(2x - 27) = 2,647.50
10x + 15x - 405 = 2,647.50
25x = 3,052.50
x = 122
Step 5: We can substitute the value of x in one of the equation, to find the value of y
y = 2(122) - 27
y = 245
Final Answer: 122 adult tickets and 245 senior/child tickets were sold.
Note: We can check our solution by multiplying the number of adult tickets by $10 and the number of senior/child tickets by $7.5 to check if the total money is $2,647.50 which is true.
what are factors of 3/2
3/2 does not have any factors because it is a fraction and factors are integers that can divide a number evenly. Only integers can have factors, fractions cannot.
What is a factor of a number?Generally, A divisor of an integer n, also known as a factor of n, is an integer m that can be multiplied by another number to generate n. Another name for this concept is a factor of n. One may also state that n is a multiple of m in this particular scenario.
A number is considered to be a factor if the division of that number by that number results in no residue. If we get a product when we multiply two whole numbers, then the numbers we are multiplying are factors of the product since they are divisible by the product. In other words, we get a product when we multiply two whole numbers. Multiplication and division are the two techniques that may be used to discover factors.
Since 3/2 is a fraction, it does not have any factors since factors are integers that may evenly divide a number. Since 3/2 is a fraction, it does not have any factors. Only integers are capable of having factors; fractions are unable to do so.

What is the effect on the graph of f(x) = || when the function is changed to
g(r) =
(-1)|?
Answer: The function f(x) = || is the absolute value function of x, which is defined as f(x) = |x|. The graph of this function is a "V" shape, with the vertex at the origin (0,0) and the lines x = 0 and y = 0 as the asymptotes. The graph of f(x) starts at the origin and increases as x increases or decreases, but never reaches x-axis.
The function g(r) = (-1)|r| is the absolute value function of r, multiplied by -1. The effect of multiplying the function by -1 is to reflect the graph of f(x) across the x-axis. So the graph of g(r) will be a "V" shape, with the vertex at the origin, and the lines x = 0 and y = 0 as the asymptotes. The graph of g(r) starts at the origin and decreases as r increases or decreases, but never reaches x-axis.
In summary, the effect of the change on the graph of f(x) = || is that it will be reflected across the x-axis.

A rental car company charges $43 per day to rent a car and $0.10 for every mile driven. Alyssa wants to rent a car, knowing that: She plans to drive 275 miles. She has at most $100 to spend. Which inequality can be used to determine dd, the maximum number of days Alyssa can afford to rent for while staying within her budget?
Answer: The inequality that can be used to determine the maximum number of days Alyssa can afford to rent for while staying within her budget is:
43d + 0.1(275) <= 100
Step-by-step explanation: The rental car company charges $43 per day to rent a car and $0.10 for every mile driven.
Alyssa wants to rent a car for d days, and she plans to drive 275 miles.
The cost of renting the car for d days is 43d, and the cost of driving 275 miles is 0.1(275)
To determine the maximum number of days Alyssa can afford to rent for while staying within her budget, we can write the inequality:
43d + 0.1(275) <= 100
This inequality represents the total cost of renting the car and the cost of driving, which should be less than or equal to $100 (Alyssa's budget)
On solving the inequality we can determine the maximum days Alyssa can afford.

The Locust Grove gymnasium has the dimensions 54 yd. x 40 yd. If each person takes up 2.5 square
feet, how many could you fit on the gym floor for an event?
Answer:
you could fit 7776 people on the gym floor for an event.
Step-by-step explanation:
The Locust Grove gymnasium has an area of 54 yd x 40 yd = 2160 square yards. To find the number of people that can fit on the gym floor, we need to convert the area of the gym floor to square feet and divide it by the number of square feet each person takes up.
We know that 1 yard = 3 feet, so we have to convert the area of the gymnasium in square yards to square feet by multiplying it by (3*3) = 9.
So the area of the gymnasium in square feet is 2160*9 = 19440 square feet.
To find the number of people that can fit on the gym floor, we divide the area of the gym floor by the number of square feet each person takes up.
19440 square feet / 2.5 square feet/person = 7776 people
