We are asked to simplify the expression
.
![\triangle~\fbox{\bf{KEY:}}](https://tex.z-dn.net/?f=%5Ctriangle~%5Cfbox%7B%5Cbf%7BKEY%3A%7D%7D)
That's exactly what we need to do - combine like terms.
So, we subtract:
![\star~\large\pmb{7x^2-x^2}](https://tex.z-dn.net/?f=%5Cstar~%5Clarge%5Cpmb%7B7x%5E2-x%5E2%7D)
Which gives us:
![\star~\large\pmb{6x^2}](https://tex.z-dn.net/?f=%5Cstar~%5Clarge%5Cpmb%7B6x%5E2%7D)
Hope it helps you out! :D
