Answer:
a + b = √3ab (or) a = -b
Step-by-step explanation:
a^3 + b^3 = 0
(a + b) (a^2 - ab + b^2 ) = 0
Case 1
a + b = 0 (second bracket goes to LHS and becomes 0)
a = -b
Case 2
a^2 - ab + b^2 = 0 (first bracket goes to LHS and becomes 0)
a^2 + b^2 = ab
(a + b)^2 - 2ab = ab
(a + b)^2 = 3ab
a + b = √3ab
