Answer:
Step-by-step explanation:
3x²-5x + 4 ---------- (1)
3x²-x² + 2x - 4 = 2x²+ 2x - 4 ------------ (2)
If we subtract it would be :
(3x²- 5x + 4) - (2x²+2x-4) = x² - 7x + 8
If we add it would be ;
(3x²-5x+4) + (2x²+2x-4) = 5x²-3x ± 0 [ 4-4 = 0]

Step-by-step explanation:
=3x^2-5x+4
=3x^2-x2+2x-4 = 2x^2+2x-4
=(2x^2+2x-4) - (3x^2-5x+4)
= 2x^2+2x-4 - 3x^2-5x+4
= -x^2 - 3x
= -x( x + 3)
