Spud has done it again. He's lost another polynomial function. This one was a cubic, written in standard form. He knows that there were two complex zeros, and one real zero, −1. What could his original function have been?

Use the three roots to find the individual polynomials that make up the cubic equation.

Now multiply the two complex polynomials.

Now multiply this equation by .
