Answer:

= - x^2 + 4x  - 14

Step-by-step explanation:

(2x^2+6x−7)−(3x^2+3x−1)+(x−8)​

= (2x^2+6x−7   )    −3x^2   -3x  +1     +   (x−8)​

= (2x^2+6x−7   )    −3x^2   -3x  +1     +   x−8​

= (2x^2+6x−7   )    −3x^2   -2x - 7

= 2x^2+6x−7       −3x^2   -2x - 7

= 2x^2+6x−7       −3x^2   -2x - 7

= - x^2 + 4x  - 14
