*y*+ 2*y*+*y*^{2}+ 5 +*y*3

*y*^{2}+ 2*xy*+ 1 + 3*x*+*y*+ 2*x*^{2}3

*xy*+ 5*x*+ 2 + 3*y*+*x*+ 44

*m*+ 2*mn*+*m*^{2}+*m*+ 3*m*^{2}

Combine like terms.

3*y* + 2*y* + *y* + *y*^{2} + 5

6*y* + *y*^{2} + 5

Arrange from the highest to the lowest power.

*y*^{2} + 6*y* + 5

Is there any way to combine terms?

Remember, you can only add terms if they have the exact same variable.
