$(6 x - 4 x^{2} - 7 x^{3}) + (9 x^{2} - 5 x)$

Step 1

Remove parentheses.

$6 x - 4 x^{2} - 7 x^{3} + 9 x^{2} - 5 x$

Step 2

Subtract $5 x$ from $6 x$ .

$- 4 x^{2} - 7 x^{3} + 9 x^{2} + x$

Step 3

Add $- 4 x^{2}$ and $9 x^{2}$ .

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

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