Solving for variable 'x'.

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

Divide each side by '8'.
1.875 + -0.75x + x2 = 0

Move the constant term to the right:

Add '-1.875' to each side of the equation.
1.875 + -0.75x + -1.875 + x2 = 0 + -1.875

Reorder the terms:
1.875 + -1.875 + -0.75x + x2 = 0 + -1.875

Combine like terms: 1.875 + -1.875 = 0.000
0.000 + -0.75x + x2 = 0 + -1.875
-0.75x + x2 = 0 + -1.875

Combine like terms: 0 + -1.875 = -1.875
-0.75x + x2 = -1.875

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 = -1.875 + 0.140625

Reorder the terms:
0.140625 + -0.75x + x2 = -1.875 + 0.140625

Combine like terms: -1.875 + 0.140625 = -1.734375
0.140625 + -0.75x + x2 = -1.734375

Factor a perfect square on the left side:
(x + -0.375)(x + -0.375) = -1.734375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
