Multiply the polynomials?
(x^2+x)(2x^3-x+1)
= 2x^5 - x^3 + x^2 + 2x^4 -x^2 + x
= 2x^5 + 2x^4 - x^3 + x

To multiply polynomials, all u need to do is dat u take each element of a polynomial and multiply with each element of the other polynomial.Then u add all that you get.For the question, the answer is:
x^2*2x^3+x^2*(-x)+x^2*1+x*2x^3+x*(-x)+x*1
=2x^5-x^3+x^2+2x^4-x^2+x
=2x^5+2x^4-x^3+2x^2+x
and that is the answer.
