Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
-0.175 + 1.8x + x2 = 0

Move the constant term to the right:

Add '0.175' to each side of the equation.
-0.175 + 1.8x + 0.175 + x2 = 0 + 0.175

Reorder the terms:
-0.175 + 0.175 + 1.8x + x2 = 0 + 0.175

Combine like terms: -0.175 + 0.175 = 0.000
0.000 + 1.8x + x2 = 0 + 0.175
1.8x + x2 = 0 + 0.175

Combine like terms: 0 + 0.175 = 0.175
1.8x + x2 = 0.175

The x term is 1.8x.  Take half its coefficient (0.9).
Square it (0.81) and add it to both sides.

Add '0.81' to each side of the equation.
1.8x + 0.81 + x2 = 0.175 + 0.81

Reorder the terms:
0.81 + 1.8x + x2 = 0.175 + 0.81

Combine like terms: 0.175 + 0.81 = 0.985
0.81 + 1.8x + x2 = 0.985

Factor a perfect square on the left side:
(x + 0.9)(x + 0.9) = 0.985
