a and b are positive integers. Dividing a^{2} + b^{2} by a + b we obtain the quotient as q and the remainder as r.
Determine analytically all possible pairs (a, b) such that q^{2} + r = 2547
I have made the assumption that r is the numerator of the remainder of the division result, ie. the proper fraction of the mixed number [Q r/(a+b) ]. For if r were the remainder, in order for the equation, q2 + r, to equal a whole number, as is 2547, r would need be zero.
Two of the pairs are (24, 61) and, of course, (61, 24).
