x-intercept means f(x) = 0

(x-8)(x+9) = 0 ⇒ x = 8 or x = - 9

There are two points which are x-intercepts. They are (8,0) and (-9,0).

What is (n+2) / -8=-4
Travka [436]

\frac{n +2}{-8} =-4      Multiply -8 on both sides

\frac{n +2}{-8} (-8)=-4(-8)

n + 2 = 32       Subtract 2 on both sides

n + 2 - 2 = 32 - 2

n = 30
