Bad White [126]
For this case you must simplify the expression respecting the rules of multiplication of mathematics.
 The steps to simplify the expression are the following:
 First multiply what is in the parentheses
  -2x ^ 2 (x - 5) + x (2x ^ 2 - 10x) + x
  -2x ^ 3 + 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x
 Then add the terms that have the same exponent
 (-2x ^ 3 + 2x ^ 3) + (10x ^ 2 - 10x ^ 2) + x
