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?

As exemplified by (3,5), (6,10), (9,15),(12,20), any integral multiple of one solution is another solution, so each such family of a given ratio has infinitely many members.
