Question

yo, does anyone know what's considered like terms in this expression? 3n + 18 - 7n + 3 + 5m

Answer 1

Like terms are terms that share common factors.

Constants: Plain numbers. Ex. 1,1.2, (4/3), etc.
Variables: You group these according to the variable.

\(n~\text{with}~n, ~xy~\text{with}~xy,~5a^2b~\text{with}~4a^2b\)

Does this make sense?

Answer 2

You should sum the sames !
Do you know the sames ?;)
The sames :
have :
same power x^2 and 1000x^2
same word x and x 2x and 800x
So sames there are :
3n and -7n
18 and 3
and 5m is alone !
So sum them ;):
-7n+3n+5m+18+3=-4n+5m+21
Got it ?;)

Answer 3

Thanks guys got it! :)
