Answer:
x^2 -81
Step-by-step explanation:
(x+9)(x-9)
FOIL
first x*x = x^2
outer -9x
inner 9x
last -9*9 = -81
Add them together
x^2 -9x+9x -81
Combine like terms
x^2 -81
Answer:
1 second
Step-by-step explanation:
y = -16x² + 32x
y = -16(x² - 2x)
y = -16(x² - 2(x)(1) + 1² - 1²)
y = -16(x - 1)² + 16
Max height is when (x-1) = 0
So x = 1
