Answer:
4-4x-2x^2
Step-by-step explanation:
Sum of 4+3x and 5-4x+2x
= 4+3x+5-4x+2x
= 4+5+3x+2x-4x
= 9+5x-4x
= 9+1x
Sum of 3x^2-5x and -x^2+2x+5
= 3x^2-5x+(-x^2+2x+5)
= 3x^2-5x-x^2+2x+5
= 3x^2-x^2-5x+2x+5
= 2x^2-3x+5
On subtracting 2x^2-3x+5 from 9+1x
= 9-1x-(2x^2-3x+5)
= 9-1x-2x^2+3x-5
= 9-5-1x-3x-2x^2
= 4-4x-2x^2
