Question

4. From the sum of 1 + 2x and x2 - 2x + 11, subtract
the sum of x2 – 9x and -2.x2 + x + 10.​

Answer 1

Answer:

I hope

Step-by-step explanation:

1+2x + x square - 2x + 11 - ( x square - 9x+ -2x square + 10)

=12 + x square- ( -x square -8x + 10)

=12+ x square + x square + 8x - 10

= 2+ 2x square +8x

Answer 2

Answer:

$2x^2+8x+2$ is your  answer.

Step-by-step explanation:

(1+2 x+$x^2$-2 x+11) = $x^2 + 12$

(x^2-9 x-2 x^2 +x+10) = $10-8x-x^2$

( $x^2 + 12$ )-($10-8x-x^2$)

$2x^2+8x+2$
