Answer:
Addition
4+3x+5-4x+2x²
=4+5+3x-4x+2x²
=9-x+2x²
Addition
3x²-5x+(-x²+2x+5)
=3x²-5x-x²+2x+5
=3x²-x²-5x+2x+5
=2x²-3x+5
Subtraction
(9-x+2x²)-(2x²-3x+5)
= 9-x+2x²-2x²+3x-5
=9-5-x+3x+2x²-2x²

Answer:
4x^2-2x+14
Step-by-step explanation:
Addition
4+3x+5-4x+2x^2
= 3x-4x+4+5+2x^2
= -x+9+2x^2
Addition
3x^2-5x+-x^2+2x+5
= 3x^2-x^2-5x+2x+5
= 2x^2-3x+5
Subtraction
2x^2-3x+5--x+9+2x^2
= 2x^2+2x^2-3x+x+5+9
= 4x^2-2x+14
