Question

The zeros of a polynomial function are 1/2, -4 and -1. What are the factors?

Answer 1

The factors are;

(x + 4) , (x + 1) and (2x-1)

Explanation:

Given the zeros, we want to get the factors

To get the zeros, we simply equate the factors to zero and solve for x

so for x = 1/2

we can have x - 1/2 = 0

multiply through by 2

= 2x - 1

for x = -4

x + 4

for x = -1

x + 1

So the factors are;

(x + 1) , (x + 4) and (2x-1)
