Question
Perform the indicated operation.$$\begin{array}{r}-3 x y+7 x y^{2}+5 x^{2} y \\+\left(-8 x y-11 x y^{2}+3 x^{2} y\right) \\\hline\end{array}$$
Step 1
The operation inside the bracket is addition, so the signs of the terms inside the bracket will not change. We get: $$-3 x y+7 x y^{2}+5 x^{2} y -8 x y-11 x y^{2}+3 x^{2} y$$ Show more…
