Answer:
(i) -2xy + 3x²
(ii) 9x²y - 8xy²
(iii) 11mn - 4
(iv) a+b+6
Step-by-step explanation:
(i) 5xy + (-7xy) + 3x²
= -2xy + 3x²
(ii) 4x²y + (-3xy²) + (-5xy²) + 5x²y
9x²y + (-8xy²)
= 9x²y - 8xy²
(iii) (-7mn) + 5 + 12mn + 2 + 8mn + (- 8) + (-2mn) + (-3)
= 11mn - 4
(iv) a+b-3 + b-a+3 + a-b+3
= a + b + 6
