Question

What are the zeros of the polynomial function: f(x) = x^3 + 2x^2 – 24x ?

Answer 1

take x as a common factor then solve the quadratic

Answer 2

x^3 + 2x^2 – 24x=0
x(x^2+2x-24)=0
x(x+6)(x-4)=0

x=0 x=-6 x=4

Answer 3

take note of how diyadiya solved the problem, that is a useful way to approach it.
