Can anyone help me solve this question..its urgent ^^ thank you

For each of the following polynomial functions, determine if each of x=-1, x=0 and/or x=2 is a zero of the polynomial and, if so, whether its muliplicity is even or odd.

1.) f(x)= x^4+2x^3+2x^2

2.) g(x)=5x^2-5x-10

3.) h(x)= x^3(x+1)^4(x+2)

4.) The graph of p(x) is :
