Solving for variable 'x'.

Begin completing the square.  Divide all terms by
0.2 the coefficient of the squared term: 

Divide each side by '0.2'.
25600 + 250x + x2 = 0

Move the constant term to the right:

Add '-25600' to each side of the equation.
25600 + 250x + -25600 + x2 = 0 + -25600

Reorder the terms:
25600 + -25600 + 250x + x2 = 0 + -25600

Combine like terms: 25600 + -25600 = 0
0 + 250x + x2 = 0 + -25600
250x + x2 = 0 + -25600
