Suppose a and b are positive integers. We all know that aČ+2ab+bČ is a perfect square. Give an example where also aČ+ab+bČ is a perfect square. How many such examples exist?

But a=3 & b=5 does not satisfy the equations which you have derived. Couldn't find anything wrong with your derivation either!!!
