Is there a quick way to find integer values of x that give integer values for y?
(x^2-R)/(P-2x)=y
sqrt(R) rounded down<x<P/2
an equivalent equation is
x^2+Px+R=y y= a perfect square
sqrt(x^2+Px+R)= integer
P and R are integer values. They are very large.
P=1.720901664588208977632751606930114527882871349707453690712637328347852193783039275682367157744911327176901e+106
R=1.611966555644167779663503662738501807226651661942209780569274299995114404468640924608971613224013135298666e+105
Maybe a generalized equation or a program?
