$(x^{2} - 3 x - 5 x y) + (6 x^{2} - 2 x y + x)$

Step 1

Remove parentheses.

$x^{2} - 3 x - 5 x y + 6 x^{2} - 2 x y + x$

Step 2

Add $x^{2}$ and $6 x^{2}$ .

$7 x^{2} - 3 x - 5 x y - 2 x y + x$

Step 3

Add $- 3 x$ and $x$ .

$7 x^{2} - 5 x y - 2 x y - 2 x$

Step 4

Subtract $2 x y$ from $- 5 x y$ .

$7 x^{2} - 7 x y - 2 x$

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