Form a polynomial, f(x), with real coefficients having the given degree and zeros.
Degree 3; zeros: 1 + i and 10

Hint: If x = 1+i is a root, x = 1 i must also be a root. Comples roots occur in pairs.
So (x+10), (x 1 i) and x 1 + i) must be factors.
Multiply all that out for a third order polynomial.
