For this case we have the following expression: -2x ^ 2 (x + 5) + x (2x ^ 2-10x) + x Rewriting we have: -2x ^ 3 - 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x Grouping terms with the same exponent: x ^ 3 (-2 + 2) + x ^ 2 (-10 - 10) + x -20x ^ 2 + x Rewriting: x (-20x + 1) Answer: The simple form of the expression is: x (-20x + 1)
