Question

What are the zeros of the polynomial function: f(x) = (x - 3)(x + 1)(x - 5)?

Answer 1

This function is already factored, so we don't have to take that step. To find the zeroes (roots) we set the function equal to 0, so:
(x-3)(x+1)(x-5)=0
In order for this function to equal 0, one of the factors must be equal to 0 (you can't multiply two numbers together to get 0 if neither one is 0). So you can set each factor equal to 0:
x-3=0
x+1=0
x-5=0
Solve each of these three expressions to get your roots.

Answer 2

x=3
x=-1
x=5
