Question

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

A: –3, 1, 5
B: –3, –1, –5
C: 3, –1, –5
D: 3, 1, 5

I picked A, am I correct?

Answer 1

Could you explain why, please?

Answer 2

no, to find the zeros you have to make f(x) = 0.
if you make f(x) = 0, each bracket must equal 0
so for eg. (x-3)=0
therefore, x=3
etc.

Answer 3

So C would be correct after all then, right? Just want to double check..

Answer 4

yep

Answer 5

Alright, thank you so much!~
