3x2^m + 1 = n^2 - find all values such that this is true

I'm having difficulty remembering wot to do with an equation lyk this, im pretty sure its slightly different to the last one i posted and i just cant remember or find it in my textbooks. Any help would b fantastic.

3 x (2^x) + 1 = n^2

You must find all pairs of positive integers that work for this equation.

Cant remember wot method 2 use.

Still not getting u - how do u get the actual numerical values??

n-1 or n+1 must be equal to 2^x , why?

if n-1 = 2^x ==> n= 2^x +1 BUT you gave also a 3 to deal with...
