3x-9%2B8x%5E2-x%2Bx%5E5%2Bx%5E4-3x%5E5 Start with the given expression


%28x%5E5-3x%5E5%29%2B%28x%5E4%29%2B%288x%5E2%29%2B%283x-x%29%2B%28-9%29 Group like terms


-2x%5E5%2Bx%5E4%2B8x%5E2%2B2x-9 Combine like terms


So 3x-9%2B8x%5E2-x%2Bx%5E5%2Bx%5E4-3x%5E5 simplifies to -2x%5E5%2Bx%5E4%2B8x%5E2%2B2x-9


In other words, 3x-9%2B8x%5E2-x%2Bx%5E5%2Bx%5E4-3x%5E5=-2x%5E5%2Bx%5E4%2B8x%5E2%2B2x-9 for all values of x
