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

Step 1

Subtract $6 x^{2}$ from $2 x^{2}$ .

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

Step 2

Add $8$ and $7$ .

$- 4 x^{2} - 4 x + 3 x + 15$

Step 3

Add $- 4 x$ and $3 x$ .

$- 4 x^{2} - x + 15$

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