= .
-----------------------------------

Divide both sides by 12. You will get

 = .

Take square roots from both sides. You will get

 = +/- .

 =   ----->  = +/-  + , k = 0, +/-1, +/-2, . . .   or    =  + , k = 0, +/-1, +/-2, . . . 

 =   ----->  =  + , k = 0, +/-1, +/-2, . . .   or    =  + , k = 0, +/-1, +/-2, . . . 

Answer. The solutions are

          =  + , k = 0, +/-1, +/-2, . . .

          =  + , k = 0, +/-1, +/-2, . . .

          =  + , k = 0, +/-1, +/-2, . . . 

          =  + , k = 0, +/-1, +/-2, . . .
