Step 1.1

Remove parentheses.

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

Step 1.2

Subtract $7$ from $4$ .

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

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

Step 2

Add $3 x^{4}$ and $6 x^{4}$ .

$- 8 x^{2} + 9 x^{4} + 2 x - 3$

Step 3

Reorder $- 8 x^{2}$ and $9 x^{4}$ .

$9 x^{4} - 8 x^{2} + 2 x - 3$

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