Question 1150785: For the equation (a-b)^2 + a^2 = 25, a and b are integers and a is greater than or equal to 0. List the ordered pairs that occur. Answer by ikleyn(52908) (Show Source):
Recall that 3^2 + 4^2 = 25 is the only Pythagorean triple with c^2 = 25.
It gives the list of pairs (a,b) as follows
(a,b) = (3,-1), (4,1), (3,7), (4,7).
