I was told to multiply this expression out, not sure how.
%28x%2B6%29%28x%5E3+-+x%5E2+-+5x%2B1%29
----------------
Multiply %28x%5E3+-+x%5E2+-+5x%2B1%29 by x, then by 6, and add them up.
=x%2A%28x%5E3+-+x%5E2+-+5x%2B1%29+%2B+6%2A%28x%5E3+-+x%5E2+-+5x%2B1%29
=x%5E4+-+x%5E3+-+5x%5E2+%2B+x+%2B+6x%5E3+-+6x%5E2+-+30x+%2B+6
=x%5E4+%2B+5x%5E3+-+11x%5E2+-+29x+%2B+6
