Question

Write a polynomial function in standard form with the given zeros x=1,-1,-2

Answer 1

y = x³ +2x² -x -2

Explanation:

A polynomial with root q has a factor (x -q). The factored form of the polynomial is ...

y = (x -1)(x +1)(x +2)

y = (x² -1)(x +2) . . . . . . partial simplification

y = x³ +2x² -x -2
