Yes. I assume you mean (x2 + y2) / (a2 + b2) = 1. Set all the variables to the same value - for example, all equal to one - and you have a valid solution.

It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
Four squared plus 188,898 minus 17,798 plus 188,898 = 360,014
