Question

What are the zeros of the function? What are their multiplicities?
f(x)=3x^3+15x^2+18x

~ The numbers 3, -2, and 0 are zeros of multiplicity 2.
~ The numbers 3, -2, and 0 are zeros of multiplicity 1.
~ The numbers -3, -2, and 0 are zeros of multiplicity 1.
~ The numbers -3, -2, and 0 are zeros of multiplicity 2.

Answer 1

f(x)=3 x^3+15 x^2+18 x
=3 x(x^2+5 x+6)
