Solving
300 + -13x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-300' to each side of the equation.
300 + -13x + -300 + x2 = 0 + -300

Reorder the terms:
300 + -300 + -13x + x2 = 0 + -300

Combine like terms: 300 + -300 = 0
0 + -13x + x2 = 0 + -300
-13x + x2 = 0 + -300

Combine like terms: 0 + -300 = -300
-13x + x2 = -300

The x term is -13x.  Take half its coefficient (-6.5).
Square it (42.25) and add it to both sides.

Add '42.25' to each side of the equation.
-13x + 42.25 + x2 = -300 + 42.25

Reorder the terms:
42.25 + -13x + x2 = -300 + 42.25

Combine like terms: -300 + 42.25 = -257.75
42.25 + -13x + x2 = -257.75

Factor a perfect square on the left side:
(x + -6.5)(x + -6.5) = -257.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
