$(x^{2} y - 3 x^{2} + y) + (3 y - 2 x^{2} y)$

Step 1

Remove parentheses.

$x^{2} y - 3 x^{2} + y + 3 y - 2 x^{2} y$

Step 2

Subtract $2 x^{2} y$ from $x^{2} y$ .

$- x^{2} y - 3 x^{2} + y + 3 y$

Step 3

Add $y$ and $3 y$ .

$- x^{2} y - 3 x^{2} + 4 y$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
