Factor Theorem.

given the x+2 and 3x-1 are factors of the expression 3x^3-10x^2+px+q, find the values of p and q. Hence, find the third factor of the expression.
I already found that p=-27 and q=10 but i don't know how to find a factor. It would be nice if someone explained.

If you find p and q, then divide 3x^3-10x^2-27x+10 by (x+2)(3x-1) and you get the  thrid factor:  x-5
