Your question isn't stated clearly, but if you mean
one leg is a2-b2 and the other leg is 2ab, then the hypotenuse is
sqrt[a4 - 2a2b2 + b4 - 4a2b2] = a2 + b2

This is confusing as written. It looks like "a" and "b" are supposed to be variables referring to the length of the sides. If so, then what are "aa" and "bb"?05/28/19
