formula for a function..help please!!

1. Write the formula for the function that has degree 3 and zeros of -1,2,and 5 with a lead coefficient of 1 (keep answers in the factored form)? f(x)=

2. write the formula for the function that had degree 4 and zeros of -4,3(multiplicty2) and 4 with a lead coefficient of -1(keep answer in factored form)? f(x)=

What have you tried so far?

I just wasnt sure where to even start but I think I got it I think 1. f(x)=1(x+1)(x-2)(x-5) and 2. (f)x=-1(x+4)(X-3)(x-3)(x-4)

For a root at 3(multiplicty2) - you should have a factor of (x - 3)²
