Pre-Calc: A polynomial with a specified complex zero

Hello! I am currently stuck on a homework question and I keep getting it wrong. Here is what the question is asking:

Find a polynomial with integer coefficients that satisfies the given conditions.

R has degree 4 and zeros 3 − 3i and 2, with 2 a zero of multiplicity 2.

Here is the work that I have done:







So R(x)=x4+2x3-2x2-48x+72

When I go to check it it says it's wrong. I have checked the math over and over and have done it 4 time but end up with the same answer. I appreciate your time in advance!
