2x²-10x+1
to complete the square you add    >    (10/2)²  = 25
   then divide 25 by the coefficient of the first term
   which is 25/2
the final expression is    >        (√2 x - 5/√2)² - 25/2 + 1
  = (√2 x- 5/√2)² -23/2
to complete the square take the sqrt of 2x² & 25/2
also since you have added 25/2 to the expression
you must - 25/2 to balance up

hey Grandpa the question was just completing the square not an expression of balancing a made up equation...
