We know that a^2,b^2,c^2 are different squares. We've got these 3 equations x+y=a^2 2x+y=b^2 x+2y=c^2 Find all x,y Last edited by skipjack; March 29th, 2019 at 02:15 AM.

Any number can be written as a² or b² or c². For simplicity, let's take a = 0, x = b² and y = b².

$\displaystyle x+y=\frac{a^2 + b^2 +c^2 }{4}$ .

$y = c^2a^2$ $x = b^2a^2$ ok, now what?

$\displaystyle x=b^2a^2$ , $\displaystyle y=2a^2b^2$ and $\displaystyle 3a^2=b^2+c^2$. All the best, Integrator Last edited by Integrator; March 31st, 2019 at 07:57 AM.
