Answer:
See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h)^2 - k = 0, the vertex is (h, -k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2)^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1)^2 = 2
(x - 1)^2 - 2 = 0
The vertex is (1, -2)
5x(x+4)
Step by step
5x^2 = 5x(x) because it’s the largest you can divide by
20x =4 because 5x times by 4 = 20x
Which means 5x^2+20x = 5x^2+20x= 5x(x+4)
Answer: 33
