Question

identify the zeros of f(x) = (x + 9)(x − 4)(6x + 1).

Answer 1

Answer:

x = - 9, x = - $\frac{1}{6}$, x = 4

Step-by-step explanation:

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

(x + 9)(x - 4)(6x + 1) = 0

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 4 = 0 ⇒ x = 4

6x + 1 = 0 ⇒ 6x = - 1 ⇒ x = - $\frac{1}{6}$
