Question

Identify the zeros of f(x)= (x-7)(x+4)(3x-2) Choices:

Answer 1

second option

Explanation:

Given

f(x) = (x - 7)(x + 4)(3x - 2)

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

(x - 7)(x + 4)(3x - 2) = 0

Equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x + 4 = 0 ⇒ x = - 4

3x - 2 = 0 ⇒ 3x = 2 ⇒ x =
`(2)/(3)`

zeros are x = - 4, x =
`(2)/(3)`, x = 7
