A Nice Math Olympiad Question | You Should Know This!

[@toby6180]

You need to add that you only want INTEGER solutions. Otherwise, a can be anything, and b is readily determined, and the sums are wildly different. For example, a = 4, b = 5/9, or a = 2, b = 1.4 , etc.

[@ianyoon7336]

there are literally infinite amount of solutions

[@JJ_TheGreat]

Ah... I thought the problem was: a²+2ab+b²=9 Then: (a+b)²=9 a+b=SQRT(9) a+b=±3

[@erwinkurniadi1850]

Does anyone understand the solution for line 3. Why 18-1?

[@869dailymathematics]

You mean 18+1 ??

[@lockaltube]

wtf

[@869dailymathematics]

Shocked??
