$(4 x^{2} - 3 x + 7) + (2 x^{2} + 6 x - 8)$

Step 1

Remove parentheses.

$4 x^{2} - 3 x + 7 + 2 x^{2} + 6 x - 8$

Step 2

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

$6 x^{2} - 3 x + 7 + 6 x - 8$

Step 3

Add $- 3 x$ and $6 x$ .

$6 x^{2} + 3 x + 7 - 8$

Step 4

Subtract $8$ from $7$ .

$6 x^{2} + 3 x - 1$

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