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.
Somehow you messed up the final answer. It is just
15w^3 + 25w^2x - 5wx^2
There are no wx terms anywhere.
Yes, you are correct in simplifying the expression. The final answer should be 15w^3 + 25w^2x - 5wx^2.
To simplify the expression, you grouped the like terms together. You combined the coefficients of the same variables and kept the variable term intact. Here's a breakdown of the process:
Original expression: 23w^3 - 5w^2x + 8wx^2 - 8w^3 - 13wx^2 + 30w^2x
Grouping like terms:
(23w^3 - 8w^3) + (-5w^2x + 30w^2x) + (8wx^2 - 13wx^2)
Combining the coefficients:
15w^3 + 25w^2x - 5wx^2
So, your final answer, 15w^3 + 25w^2x - 5wx^2, is correct. Well done!
