Question

What are the zeros of the polynomial function f(x) = x(x + 5)(x – 8)?

–5, 8


0, –5, 8


5, –8


0, 5, –8

Answer 1

Option B is answer.

Explanation:

Hey there!

Given;

f(X) = X(X+5)(x-8)

According to the factor theorem, f(X) = 0;

Or, X(X+5)(x-8) = 0

Either;

x = 0

Or;

(x+5)= 0

X = -5

Or;

(x-8)= 0

x = 8.

Therefore, the zeros of the polynomial are: 0,-5,8.

Hope it helps!
