Subtract 9x^2 – 10x + 1 from -2x^2 + 4x – 10.

11x^2  −6x−9

Step-by-step explanation:

9x^2 – 10x + 1 - ( -2x^2) + 4x – 10.

The opposite of −2x^2 is 2x^2

9x^2 −10x+1+2x ^2 +4x−10

Combine 9x^2  and 2x^2  to get 11x^2 .

11x^2 −10x+1+4x−10

Combine −10x and 4x to get −6x.

11x^2 −6x+1−10

Subtract 10 from 1 to get −9.

11x^2  −6x−9

step-by-step explanation:
