Question

Re-write the quadratic function below in Standard Form
y=−2(x−8)(x−2)

Answer 1

y= −2x^2+20x−32

Explanation:

y = −2(x−8)(x−2)

= - 2(x^2 - 10x +16)

= - 2x^2 - (-10x)-2. 16

= - 2x^2 +20x - 32

Answer 2

y = -2(x - 8)(x - 2)

y = -2(x² -2x -8x +16)

y = -2(x² - 10x + 16)

y = -2x² + 20x - 32
