Who can solve this math problem? Let it be math majors ;)

I'm thinking of a polynomial. The degree is 4. There is an imaginary zero, and it is 1+3i. The only real zero I have is -5. f(1) = -45. Name this polynomial.

Good luck. ;)

P.S. This was a tricky pre-calculus problem. I'm reminiscing, going through my stacks of High School work, and this one I got wrong. I never was able to solve it. Can you?
