Solution
The given expression is -5 + 2x^3 + 2x^3 - 3 + 4x^2 - 2x^2 - x^3.
First, group the like terms together:
2x^3 + 2x^3 - x^3 (these are the x cubed terms)
4x^2 - 2x^2 (these are the x squared terms)
-5 - 3 (these are the constant terms)
Then, combine each group of like terms:
(2x^3 + 2x^3 - x^3) = 3x^3
(4x^2 - 2x^2) = 2x^2
(-5 - 3) = -8
Finally, put the expression back together:
3x^3 + 2x^2 - 8
