I'm supposed to find a polynomial with specified Zeros. This is all the question told me:
Degree: 4
Zeros: 2, 0, 2, 4
I know how to do these problems when it's a degree of 3, but not 4.

When you do one for degree of 3, don't you just form 3 factors from the given 3 zeros?
Well, now you just have 4 of them
so
y = x(x+2)(x2)(x4)
