try to solve.

Hey guess what 5-2 is 3 XD

OpenStudy (anonymous):

\[5wx^2-2wx^2\] \[3wx^2\] C

OpenStudy (saifoo.khan):

you have 5 Macbooks, you gave 2 to me. so you are left with just 3.

simple method : \[wx^2(5-2) = wx^2(3) = 3wx^2\]

So you just minus the whole numbers? Like if I had \[6\omega \kappa ^{2}-3\omega \kappa ^{2} \it would = 3\omega \kappa ^{2}\]
