Solving for variable 'x'.

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

Divide each side by '50'.
-0.02 + 0.2x + x2 = 0

Move the constant term to the right:

Add '0.02' to each side of the equation.
-0.02 + 0.2x + 0.02 + x2 = 0 + 0.02

Reorder the terms:
-0.02 + 0.02 + 0.2x + x2 = 0 + 0.02

Combine like terms: -0.02 + 0.02 = 0.00
0.00 + 0.2x + x2 = 0 + 0.02
0.2x + x2 = 0 + 0.02

Combine like terms: 0 + 0.02 = 0.02
0.2x + x2 = 0.02

The x term is 0.2x.  Take half its coefficient (0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
0.2x + 0.01 + x2 = 0.02 + 0.01

Reorder the terms:
0.01 + 0.2x + x2 = 0.02 + 0.01

Combine like terms: 0.02 + 0.01 = 0.03
0.01 + 0.2x + x2 = 0.03

Factor a perfect square on the left side:
(x + 0.1)(x + 0.1) = 0.03

Calculate the square root of the right side: 0.173205081

Break this problem into two subproblems by setting 
(x + 0.1) equal to 0.173205081 and -0.173205081.

Subproblem 1

x + 0.1 = 0.173205081 Simplifying x + 0.1 = 0.173205081 Reorder the terms: 0.1 + x = 0.173205081 Solving 0.1 + x = 0.173205081 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.1' to each side of the equation. 0.1 + -0.1 + x = 0.173205081 + -0.1 Combine like terms: 0.1 + -0.1 = 0.0 0.0 + x = 0.173205081 + -0.1 x = 0.173205081 + -0.1 Combine like terms: 0.173205081 + -0.1 = 0.073205081 x = 0.073205081 Simplifying x = 0.073205081

Subproblem 2

x + 0.1 = -0.173205081 Simplifying x + 0.1 = -0.173205081 Reorder the terms: 0.1 + x = -0.173205081 Solving 0.1 + x = -0.173205081 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.1' to each side of the equation. 0.1 + -0.1 + x = -0.173205081 + -0.1 Combine like terms: 0.1 + -0.1 = 0.0 0.0 + x = -0.173205081 + -0.1 x = -0.173205081 + -0.1 Combine like terms: -0.173205081 + -0.1 = -0.273205081 x = -0.273205081 Simplifying x = -0.273205081

Solution

The solution to the problem is based on the solutions from the subproblems. x = {0.073205081, -0.273205081}
