What an excellent equation. Can be satisfied with 4 different sets of answer . If only world leaders knew about this equation, there would have been no war today. Thank you sir.
Aprendi que na equação a.b = 0, a = 0 ou b = 0. Voçe resolveu como a = 0 e b = 0, discordo. (I learned that in the equation a.b = 0, a = 0 or b = 0. You solved it as a = 0 and b = 0, I disagree.)
As a professional, you should have known that (x-y) is less than (x^2+xy+y^2). Hence, there are only two possible cases in which (x-y) takes the smaller value while x^2+xy+y^2 takes the larger value. No need for cases 3 and 4 coz they are invalid.
y^3-x^3=91 x = -6, y = -5 x = -4, y = 3 x = -3, y = 4 x = 5, y = 6
