5x%5E4%28-3x%5E2%2B8x-1%29+

5x%5E4%28-3x%5E2%29%2B5x%5E4%288x%29%2B5x%5E4%28-1%29+

-15x%5E6%2B40x%5E5-5x%5E4+

So 5x%5E4%28-3x%5E2%2B8x-1%29+ distributes to -15x%5E6%2B40x%5E5-5x%5E4+

=======================================================

%28x%5E2%2Bx%2B1%29%282x%5E3-x%5E2%2B3%29

x%5E2%282x%5E3-x%5E2%2B3%29%2Bx%282x%5E3-x%5E2%2B3%29%2B1%282x%5E3-x%5E2%2B3%29



2x%5E5-x%5E4%2B3x%5E2%2B2x%5E4-x%5E3%2B3x%2B2x%5E3-x%5E2%2B3

2x%5E5%2Bx%5E4%2Bx%5E3%2B2x%5E2%2B3x%2B3

So the answer is 2x%5E5%2Bx%5E4%2Bx%5E3%2B2x%5E2%2B3x%2B3
