If the polynomial is to have real coefficients, then complex roots must occur in conjugate pairs. Since -1+2i is a root, -1-2i must be another root.
The linear factors are (x-5) and (x+3); the quadratic factor corresponding to the two complex roots is (x^2+2x+5). The polynomial in standard form is then
