Heya.....!!^_^
Here's ur ans. ⬇
✨_____________________________________✨
↪( a+b+c ) ^3 = a^3 + b^3 + c^3 +3 ( a+b) (b+c) ( c + a)
(a/2 - b/3 +1)^3 = a^3/ 8 - b^3 / 27 + 1 + 3(a/2 -b/3) ( -b/3 + 1) (1 + a/2)
= a^3/8 - b^3/27 + 1 + 3 ( 3a - 2b) ÷6 ( -b +3) ÷ 3 ( 2 + a) ÷ 2
= a^3 /8 - b^3 / 27 + 1 + (6a - 4b) ( -b + 3) ÷ 3 ( 2+ a) ÷ 2
