The polynomial degree 3, P(x), has a root of multiplicity 2 at x = 5 and a root of multiplicity 1 at x = -1. The y-intercept is y = -10. Find a formula for P(x).

Step-by-step explanation:

Zeros of a function:

Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.

Root of multiplicity 2 at x = 5 and a root of multiplicity 1 at x = -1.

This means that

So

The y-intercept is y = -10.

This means that when . We use this to find a.

. So
