If a polynomial has 9 for a root, (x-9) is a factor of the polynomial.
A polynomial with roots -8, 9, 10, and -11, has as a factor

I don't see an easier way, so I'll grit my teeth and multiply:

That is the simplest polynomial for the answer, and it's in standard form.
Multiplying it by a factor with x to any exponent would make it a polynomial of higher degree. Multiplying it by any number, would give you another acceptable answer, but would be unnecessary extra work.
is a suitable answer.
