Expand the left hand side

\(abx^2+(a^2+b^2)x+ab=26x^2+[]x + 26\)

 

So we must have 

a*b = 26

 

a and b are integers, so the possibilities are 

a = 1   b = 26

a = 2   b = 13    

(or the same with a and b switched).

 

Hence [] must be either \(1^2+26^2\)   or  \(2^2+13^2\)

 

I'll leave you to decide which is smaler.

Don't keep repeating the same question several times within a short period of time!
