Question

What are the x-intercepts of the polynomial function

g(x) = (2x-8)(x+1)(9 – 3x)2 ?
(Hint: There should be three of them!)

Answer 1

The x intercepts are x = 4, x = -1, and x = 3.

Explanation:

`g(x)=(2x-8)(x+1)(9-3x)^(2)\\(2x-8)(x+1)(9-3x)^(2)=0\\2x-8-0\\2x=9\\x=4\\x+1=0\\x=-1\\9-3x=0\\3x=9\\x=3\\`
