Answer:

$\boxed{ \bold{ \huge{ { \sf{ - 13 {x}^{2} - 10x + 14}}}}}$

Step-by-step explanation:

$\sf{ - 9x - x - 7 {x}^{2} - 6 {x}^{2} + 8 + 6}$

Collect like terms

⇒ $\sf{ - 7 {x}^{2} - 6 {x}^{2} - 9x - x + 8 + 6}$

⇒ $\sf{ - 13 {x}^{2} - 10x + 8 + 6}$

Add the numbers

⇒ $\sf{ - 13 {x}^{2} - 10x + 14}$

Hope I helped!

Best regards!!

Answer:

Step-by-step explanation:

First distribute the 2x to get:

4x² + 10x

Then distribute the -5 to get:

-10x - 25

Then combine

4x² + 10x - 10x - 25

The 10x's will cancel leaving you:

4x² - 25
