Question

If function g has the factors (x-7) and (x + 6), what are the zeros of function g?

A
7 and 6
6 and 7
6 and 7
17 and 6

Answer 1

x =- 6, x = 7

Explanation:

Given

g(x) = (x - 7)x + 6)

To find the zeros let g(x) = 0, that is

(x - 7)(x + 6) = 0

Equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x - 7 = 0 ⇒ x = 7
