Step 1

Simplify the expression.

Tap for more steps...

Step 1.1

Multiply $- 5$ by $- 1$ .

$- 1 + 5 x - 2 x + 2 x^{2} + 7$

Step 1.2

Add $- 1$ and $7$ .

$5 x - 2 x + 2 x^{2} + 6$

$5 x - 2 x + 2 x^{2} + 6$

Step 2

Subtract $2 x$ from $5 x$ .

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

Step 3

Reorder $3 x$ and $2 x^{2}$ .

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

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