Find the root(s) of f (x) = (x + 5)3(x - 9)2(x + 1). -5 with multiplicity 3 5 with multiplicity 3 -9 with multiplicity 2 9 with multiplicity 2 -1 with multiplicity 0 -1 with multiplicity 1 1 with multiplicity 0 1 with multiplicity 1

The roots of a polynomial written in the form

Are exactly

The multiplicity of a solution is how many times the parenthesis appears in the factorization of the polynomial.

So, if we write the powers explicitly, your polynomial is written as

Which means that the solutions are:
