Somehow you messed up the final answer. It is just
15w^3 + 25w^2x - 5wx^2
There are no wx terms anywhere.
Simplify the expression
23w^3-5w^2x+8wx^2-8w^3-13wx^2+30w^2x
Group like terms so:
23w^3-8w^3= 15w^3
-5w^2x+30w^2x= 25w^2x
8wx^2-13wx^2 = -5wx^2
The final answer I got is:
15w^3+25w^2x-5wx^25wx
Is this right? I had to simplify the expression.
