i don't know how to do this with the fractions. can you please please help?

Question

simplify the expression and combine like terms.

2n^2+4m n^2-m
_______ + ______
3 3

Answer 1

I can't read that. Try writing your fractions on one line, using /

If you mean
(2n^2+4m)/3 + (n^2 -m)/3

Since 3 is a common denominator, you cann add the numerators together, and that can be rewritten as
(3n^2 + 3m)/3
Now factor out the 3 and you have just
n^2 + m
