Begin completing the square.  Divide all terms by
-28 the coefficient of the squared term: 

Divide each side by '-28'.
-0.1071428571 + 1.25x + x2 = 0

Move the constant term to the right:

Add '0.1071428571' to each side of the equation.
-0.1071428571 + 1.25x + 0.1071428571 + x2 = 0 + 0.1071428571

Reorder the terms:
-0.1071428571 + 0.1071428571 + 1.25x + x2 = 0 + 0.1071428571

Combine like terms: -0.1071428571 + 0.1071428571 = 0.0000000000
0.0000000000 + 1.25x + x2 = 0 + 0.1071428571
1.25x + x2 = 0 + 0.1071428571

Combine like terms: 0 + 0.1071428571 = 0.1071428571
1.25x + x2 = 0.1071428571

The x term is 1.25x.  Take half its coefficient (0.625).
Square it (0.390625) and add it to both sides.

Add '0.390625' to each side of the equation.
1.25x + 0.390625 + x2 = 0.1071428571 + 0.390625

Reorder the terms:
0.390625 + 1.25x + x2 = 0.1071428571 + 0.390625

Combine like terms: 0.1071428571 + 0.390625 = 0.4977678571
0.390625 + 1.25x + x2 = 0.4977678571

Factor a perfect square on the left side:
(x + 0.625)(x + 0.625) = 0.4977678571

Calculate the square root of the right side: 0.705526652

Break this problem into two subproblems by setting 
(x + 0.625) equal to 0.705526652 and -0.705526652.
