Step 1

Remove parentheses.

$- 3 x^{2} + 4 x - 1 - 5 + 4 x + 2 x^{2}$

Step 2

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

$- x^{2} + 4 x - 1 - 5 + 4 x$

Step 3

Add $4 x$ and $4 x$ .

$- x^{2} + 8 x - 1 - 5$

Step 4

Subtract $5$ from $- 1$ .

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

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