The solution of the equation 4x² - 20x + 9 = 0 will be 0.5 and 4.5.
<h3>What is a quadratic equation?</h3>
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have
The equation is given below.
x² - 5x = -9/4
Then the equation can be written as
4x² - 20x + 9 = 0
Then the factor of the equation will be
4x² - 20x + 9 = 0
4x² - 18x - 2x + 9 = 0
2x(2x - 9) -1 (2x - 9) = 0
(2x - 1)(2x - 9) = 0
Then the solution of the equation 4x² - 20x + 9 = 0 will be
x = 0.5, 4.5

Answer:
Rather than just multiplying 5/4 with 8, she has to multiply it with 3 + 8. She could put parentheses around the 3 + 8, according to PEMDAS, this would mean that the parenthesis must be solved before multiplication. The correct answer would be:
4/5x - 8 = 3
4/5x = 3 + 8
x = (3 + 8)5/4
x = 11 x 5/4
x = 55/4 or 13.75
Answer: -1
Step-by-step explanation:
Find the two coordinates first.
In this case, they are (-4, 1) and (-2, -1).
Use the following formula to calculate slope:
Substitute in the coordinates:
= 
= -1
