Question

What are the zeros of the function?
f(x)=x(x-2)(x+6)
-6
-2
0
2
6

Answer 1

2,-6, 0

Explanation:

Since you are multypling 3 terms, if you want 0 as your answer, one of the terms has to equal 0.

To get x-2 to equal 0, x has to equal 2

To get x+6 to equal 0, x has to equal -6

And also, the first x could equal 0

Answer 2

x=0, x=2, x=-6

Explanation:

f(x)=x(x-2)(x+6) is zero if x=0,

or (x-2)=0 or (x+6)=0, then

x=0, x=2, x=-6
