Solving for variable 'x'.

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

Divide each side by '0.3'.
52900 + 100x + x2 = 0

Move the constant term to the right:

Add '-52900' to each side of the equation.
52900 + 100x + -52900 + x2 = 0 + -52900

Reorder the terms:
52900 + -52900 + 100x + x2 = 0 + -52900

Combine like terms: 52900 + -52900 = 0
0 + 100x + x2 = 0 + -52900
100x + x2 = 0 + -52900

Combine like terms: 0 + -52900 = -52900
100x + x2 = -52900

The x term is 100x.  Take half its coefficient (50).
Square it (2500) and add it to both sides.

Add '2500' to each side of the equation.
100x + 2500 + x2 = -52900 + 2500

Reorder the terms:
2500 + 100x + x2 = -52900 + 2500

Combine like terms: -52900 + 2500 = -50400
2500 + 100x + x2 = -50400

Factor a perfect square on the left side:
(x + 50)(x + 50) = -50400

Can't calculate square root of the right side.

The solution to this equation could not be determined.
