Question

Subtract $-5{\mathrm{y}}^2$ from ${\mathrm{y}}^2$.

Answer 1

We have to subtract $-5{\mathrm{y}}^2$ from ${\mathrm{y}}^2$:

$$\begin{gathered} {\mathrm{y}}^2-\left(-5{\mathrm{y}}^2\right) \\ ={\mathrm{y}}^2+5{\mathrm{y}}^2 \\ =6{\mathrm{y}}^2 \end{gathered}$$

Therefore, the required answer is $6{\mathrm{y}}^2$.
