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

Divide each side by '50'.
-0.14 + 1.26x + x2 = 0

Move the constant term to the right:

Add '0.14' to each side of the equation.
-0.14 + 1.26x + 0.14 + x2 = 0 + 0.14

Reorder the terms:
-0.14 + 0.14 + 1.26x + x2 = 0 + 0.14

Combine like terms: -0.14 + 0.14 = 0.00
0.00 + 1.26x + x2 = 0 + 0.14
1.26x + x2 = 0 + 0.14

Combine like terms: 0 + 0.14 = 0.14
1.26x + x2 = 0.14

The x term is 1.26x.  Take half its coefficient (0.63).
Square it (0.3969) and add it to both sides.

Add '0.3969' to each side of the equation.
1.26x + 0.3969 + x2 = 0.14 + 0.3969

Reorder the terms:
0.3969 + 1.26x + x2 = 0.14 + 0.3969

Combine like terms: 0.14 + 0.3969 = 0.5369
0.3969 + 1.26x + x2 = 0.5369
