$- 6 x^{2} + 14 x - 4 + (- 15 x^{2} + 9 x - 11)$

Step 1

Remove parentheses.

$- 6 x^{2} + 14 x - 4 - 15 x^{2} + 9 x - 11$

Step 2

Subtract $15 x^{2}$ from $- 6 x^{2}$ .

$- 21 x^{2} + 14 x - 4 + 9 x - 11$

Step 3

Add $14 x$ and $9 x$ .

$- 21 x^{2} + 23 x - 4 - 11$

Step 4

Subtract $11$ from $- 4$ .

$- 21 x^{2} + 23 x - 15$

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