$4 x - 5 x^{2} + 9 - 2 x + 10 x^{2}$

Step 1

Subtract $2 x$ from $4 x$ .

$2 x - 5 x^{2} + 9 + 10 x^{2}$

Step 2

Add $- 5 x^{2}$ and $10 x^{2}$ .

$2 x + 5 x^{2} + 9$

Step 3

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

$5 x^{2} + 2 x + 9$

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