Asked by Helen

Can i combine the following? Explain why or why not.

5x+4x(squared)
7x(cubic)-2x+x(cubic)-5x
3xy+2y
Answered by drwls
5x + 4x^2 cannot be combined
7x^3 -2x +x^3 -5x = 8x^3 -7x (some terms were combined)
3xy +2y cannot be combined.

You can only combine terms that contain x and other variables raised to the same power(s). Constants can also be combined.
