Combine like terms 5m2n 4m n2 3 m2n Solution5m2n 4mn2 3

Combine like terms. -5m^2n + 4m n^2 - 3 m^2n =

Solution

-5m^2n + 4mn^2 - 3m^2n

To look for like terms we should look for terms with same varible with same degrees

Ex: -5m^2n and -3m^2n are like terms

whereas , 4mn^2 and 5m^2n are not like terms

So, -5m^2n + 4mn^2 - 3m^2n = ( -5m^2n - 3m^2n) + 4mn^2

= -8 m^2n + 4mn^2
