Wonderful video

After a long time I hear your voice 😊 Can you solve some IMO questions?

[@mcwulf25]

Similar to your #3. Divided first eqn by second. Then got the same (a/b) quadratic.

well, i try to solve it before watching. and i used another method. i take p = a^2 and q = ab. then b^2 = q^2/p. make changes, solved for q and get q = 5 as solution. then (a,b) = (5, 1) and (-5, -1)

[@diegosimonetti9496]

le soluzioni del sistema sono : a = 5 , - 5 e b = 1 = - 1

Shouldn't it be given that a=\=0?

[@Eggehman]

No, it's obvious
