Question

Combine the like terms and simplify :

-6m² + (-2n²) - (-m²) + 7n² + (-5m²) + 3n²

Answer 1

Combining the like terms we get :

$$\begin{gathered} =-6m^2-2n^2+m^2+7n^2-5m^2+3n^2 \\ =-6m^2+m^2-5m^2-2n^2+7n^2+3n^2 \\ =-5m^2-5m^2-2n^2+7n^2+3n^2 \\ =-10m^2+5n^2+3n^2 \\ =-10m^2+8n^2 \end{gathered}$$
