Given that f(x) = {{{x^6+x^5-6x^4+7x^2-21x-18}}} has -1 as a zero of multiplicity 2, 2 as a zero, and -3 as a zero, find all other zeros?

I am stuck on where to even begin?

That would depend on what you know. What tools have you?

Decartes Rule of Signs?
Horners Method?
Rational Root Theorem?

f(x) = {{{x^6+x^5-6x^4+7x^2-21x-18}}}

Are those curly braces supposed to mean something?


-1 as a zero of multiplicity 2,
2 as a zero,
-3 as a zero

-1, 2, and -3 are NOT zeros of the function f(x) = x^6 + x^5 - 6x^4 + 7x^2 - 21x - 18
