$(7 x^{3} - 2 x^{2} + 3) + (x^{2} - x - 5)$

Step 1

Remove parentheses.

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

Step 2

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

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

Step 3

Subtract $5$ from $3$ .

$7 x^{3} - x^{2} - x - 2$

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