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

Step 1

Remove parentheses.

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

Step 2

Add $3 x^{2}$ and $4 x^{2}$ .

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

Step 3

Subtract $3 x$ from $2 x$ .

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

Step 4

Add $- 5$ and $7$ .

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

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