$(3 x + 5 x^{2} - 1) + (13 - 20 x + x^{2})$

Step 1

Remove parentheses.

$3 x + 5 x^{2} - 1 + 13 - 20 x + x^{2}$

Step 2

Subtract $20 x$ from $3 x$ .

$- 17 x + 5 x^{2} - 1 + 13 + x^{2}$

Step 3

Add $5 x^{2}$ and $x^{2}$ .

$- 17 x + 6 x^{2} - 1 + 13$

Step 4

Simplify the expression.

Step 4.1

Add $- 1$ and $13$ .

$- 17 x + 6 x^{2} + 12$

Step 4.2

Reorder $- 17 x$ and $6 x^{2}$ .

$6 x^{2} - 17 x + 12$

$6 x^{2} - 17 x + 12$

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