$(3 x^{2} - x + 1) + (15 - 9 x - 2 x^{2})$

Step 1

Remove parentheses.

$3 x^{2} - x + 1 + 15 - 9 x - 2 x^{2}$

Step 2

Subtract $2 x^{2}$ from $3 x^{2}$ .

$x^{2} - x + 1 + 15 - 9 x$

Step 3

Subtract $9 x$ from $- x$ .

$x^{2} - 10 x + 1 + 15$

Step 4

Add $1$ and $15$ .

$x^{2} - 10 x + 16$

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