%289x%5E2+-8x+%2B+1%29%288x+-+1%29

%288x+-+1%29%289x%5E2+-8x+%2B+1%29

8x%289x%5E2+-8x+%2B+1%29+-+1%289x%5E2+-8x+%2B+1%29

8x%289x%5E2%29%2B8x%28+-8x%29%2B8x%281%29+-+1%289x%5E2%29-1%28+-8x%29-1%281%29

72x%5E3-64x%5E2%2B8x+-+9x%5E2%2B8x-1

72x%5E3-73x%5E2%2B16x-1

So %289x%5E2+-8x+%2B+1%29%288x+-+1%29 expands out to 72x%5E3-73x%5E2%2B16x-1

In other words %289x%5E2+-8x+%2B+1%29%288x+-+1%29=72x%5E3-73x%5E2%2B16x-1
