%285x%5E2-3x+%2B+2%29+%2B+%28-3x%5E2-5x-8%29-%28x%5E2+%2B+3x-10%29 Start with the given expression


5x%5E2-3x+%2B+2-3x%5E2-5x-8-x%5E2-3x+%2B+10 Distribute the negative



%285x%5E2-3x%5E2-x%5E2%29%2B%28-3x-5x-3x%29%2B%282-8%2B10%29 Group like terms


x%5E2-11x%2B4 Combine like terms


So the expression %285x%5E2-3x+%2B+2%29+%2B+%28-3x%5E2-5x-8%29-%28x%5E2+%2B+3x-10%29 simplifies to x%5E2-11x%2B4
