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

Step 1

Remove parentheses.

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

Step 2

Subtract $2 x^{2}$ from $6 x^{2}$ .

$4 x^{2} + 7 x + 5 + 9 x$

Step 3

Add $7 x$ and $9 x$ .

$4 x^{2} + 16 x + 5$

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