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

Divide each side by '-8'.
1.75 + -0.125x + x2 = 0

Move the constant term to the right:

Add '-1.75' to each side of the equation.
1.75 + -0.125x + -1.75 + x2 = 0 + -1.75

Reorder the terms:
1.75 + -1.75 + -0.125x + x2 = 0 + -1.75

Combine like terms: 1.75 + -1.75 = 0.00
0.00 + -0.125x + x2 = 0 + -1.75
-0.125x + x2 = 0 + -1.75

Combine like terms: 0 + -1.75 = -1.75
-0.125x + x2 = -1.75

The x term is -0.125x.  Take half its coefficient (-0.0625).
Square it (0.00390625) and add it to both sides.

Add '0.00390625' to each side of the equation.
-0.125x + 0.00390625 + x2 = -1.75 + 0.00390625

Reorder the terms:
0.00390625 + -0.125x + x2 = -1.75 + 0.00390625

Combine like terms: -1.75 + 0.00390625 = -1.74609375
0.00390625 + -0.125x + x2 = -1.74609375

Factor a perfect square on the left side:
(x + -0.0625)(x + -0.0625) = -1.74609375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
