Solving for variable 'x'.

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

Divide each side by '4'.
-0.5 + 0.75x + x2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + 0.75x + 0.5 + x2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + 0.75x + x2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + 0.75x + x2 = 0 + 0.5
0.75x + x2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
0.75x + x2 = 0.5

The x term is 0.75x.  Take half its coefficient (0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
0.75x + 0.140625 + x2 = 0.5 + 0.140625

Reorder the terms:
0.140625 + 0.75x + x2 = 0.5 + 0.140625

Combine like terms: 0.5 + 0.140625 = 0.640625
0.140625 + 0.75x + x2 = 0.640625

Factor a perfect square on the left side:
(x + 0.375)(x + 0.375) = 0.640625

Calculate the square root of the right side: 0.80039053

Break this problem into two subproblems by setting 
(x + 0.375) equal to 0.80039053 and -0.80039053.

Subproblem 1

x + 0.375 = 0.80039053 Simplifying x + 0.375 = 0.80039053 Reorder the terms: 0.375 + x = 0.80039053 Solving 0.375 + x = 0.80039053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + x = 0.80039053 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + x = 0.80039053 + -0.375 x = 0.80039053 + -0.375 Combine like terms: 0.80039053 + -0.375 = 0.42539053 x = 0.42539053 Simplifying x = 0.42539053

Subproblem 2

x + 0.375 = -0.80039053 Simplifying x + 0.375 = -0.80039053 Reorder the terms: 0.375 + x = -0.80039053 Solving 0.375 + x = -0.80039053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + x = -0.80039053 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + x = -0.80039053 + -0.375 x = -0.80039053 + -0.375 Combine like terms: -0.80039053 + -0.375 = -1.17539053 x = -1.17539053 Simplifying x = -1.17539053
