Looks like you have some possible candidates.
Verify they are zeros by plugging them into the equation.

Once you have a zero, you can divide the original polynomial by the factor.
As an example, if x=12 was a zero , then x-12 is a factor of the polynomial and I could use polynomial long division to reduce the degree of the polynomial by 1.
