$(11 x + 2 x^{2}) + (- 7 x - 3 x^{2} + 4)$

Step 1

Remove parentheses.

$11 x + 2 x^{2} - 7 x - 3 x^{2} + 4$

Step 2

Subtract $7 x$ from $11 x$ .

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

Step 3

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

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

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