2 the coefficient of the squared term: 

Divide each side by '2'.
-300 + 0.5x + x2 = 0

Move the constant term to the right:

Add '300' to each side of the equation.
-300 + 0.5x + 300 + x2 = 0 + 300

Reorder the terms:
-300 + 300 + 0.5x + x2 = 0 + 300

Combine like terms: -300 + 300 = 0
0 + 0.5x + x2 = 0 + 300
0.5x + x2 = 0 + 300

Combine like terms: 0 + 300 = 300
0.5x + x2 = 300

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
0.5x + 0.25 + x2 = 300 + 0.25
