Question

Identify the zeros of the polynomial function N(x) = 1/2(x-1)(x+3)

Answer 1

x = - 3, x = 1

Explanation:

Given

n(x) =
`(1)/(2)` (x - 1)(x + 3)

To obtain the zeros, equate n(x) to zero, that is

`(1)/(2)` (x - 1)(x + 3) = 0

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1
