Which polynomial expression in factored form has 2 as a leading coefficient with −1, 3, and −5 as zeros?

a) 2(x + 1)(x − 3)(x + 5)
b) 2(x − 1)(x + 3)(x − 5)
c) 2x(x + 1)(x − 3)(x + 5)
d) 2x(x − 1)(x + 3)(x − 5)

First, lets find the factors that take the form (x-a), where a is the zero.

-1 is a zero. Thus, , aka , is a factor.

3 is a zero. Thus, is a factor.

-5 is a zero. Thus, , aka , is a factor.

Matching these factors with the possible answer choices, we can safely see that either A or C is possible.

x is not a factor because that means the polynomial will have a zero of 0, which is not stated in the question. This eliminates C and D.

This leaves us with answer choice A.

your answer is a
