$(7 x^{2} - 11 + 16 x) + (5 x - 3 x^{2} - 7)$

Step 1

Remove parentheses.

$7 x^{2} - 11 + 16 x + 5 x - 3 x^{2} - 7$

Step 2

Subtract $3 x^{2}$ from $7 x^{2}$ .

$4 x^{2} - 11 + 16 x + 5 x - 7$

Step 3

Subtract $7$ from $- 11$ .

$4 x^{2} + 16 x + 5 x - 18$

Step 4

Add $16 x$ and $5 x$ .

$4 x^{2} + 21 x - 18$

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