Hi guys, so i have a question for you ! 2n^2 + (8/3)n - (5/3) = a^2 where a is a positive integer For which values of n, is this true ?
Bonus : Let a,b,c be three integers (a is non-zero), for which values of n, this equation is true: an^2+bn+c=d^2 with d a positive integer.
Hope to you !
P.S. : n is a positive integer everytime
