How to find the zeros of this function?

Question

Y = x(x + 2)(x + 3)

Answer 1

y = x (x + 2) (x + 3)

f (x ) = x ( x + 2) (x + 3)

From the factor therom

When x  - c  is a factor of the polynomial then f (c ) = 0.

f (x ) = x (x + 2)(x + 3)

x = 0 , x + 2 = 0 and x + 3 = 0

x = 0 , x = -2 and x = -3

Zeros of the function are x = 0 , -2 and -3.
