$(3 x^{2} + 2 x + 1) + (- 3 + 2 x - x^{2})$

Step 1

Remove parentheses.

$3 x^{2} + 2 x + 1 - 3 + 2 x - x^{2}$

Step 2

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

$2 x^{2} + 2 x + 1 - 3 + 2 x$

Step 3

Add $2 x$ and $2 x$ .

$2 x^{2} + 4 x + 1 - 3$

Step 4

Subtract $3$ from $1$ .

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

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