Answer 1

Answer:

sum of first two pairs

3x^2-6+5x + 2x+5-7x^2

3x^2-6+5x+2x+5-7x^2

3x^2+5x+2x-7x^2-6+5

3x^2-7x^2+5x+2x-6+5

4x^2+7x-1

sum of second pairs

x^2+2x+9 + -2x^2-11+12x

x^2+2x+9-2x^2-11+12x

x^2+2x-2x^2+12x+9-11

x^2-2x^2+2x+12x+9-11

-x^2+14x-2

subtraction of two pairs are as follows

4x^2+7x-1 - -x^2+14x-2

4x^2+7x-1+x^2+14x-2

4x^2+7x+x^2+14x-1-2

4x^2+x^2+7x+14x-1-2

5x^2+21x-3
