Combine like terms: 14x + -14x = 0
-1 + 6x + -16x2 = 0 + 16x2 + -16x2
-1 + 6x + -16x2 = 16x2 + -16x2

Combine like terms: 16x2 + -16x2 = 0
-1 + 6x + -16x2 = 0

Begin completing the square.  Divide all terms by
-16 the coefficient of the squared term: 

Divide each side by '-16'.
0.0625 + -0.375x + x2 = 0

Move the constant term to the right:

Add '-0.0625' to each side of the equation.
0.0625 + -0.375x + -0.0625 + x2 = 0 + -0.0625

Reorder the terms:
0.0625 + -0.0625 + -0.375x + x2 = 0 + -0.0625

Combine like terms: 0.0625 + -0.0625 = 0.0000
0.0000 + -0.375x + x2 = 0 + -0.0625
-0.375x + x2 = 0 + -0.0625

Combine like terms: 0 + -0.0625 = -0.0625
-0.375x + x2 = -0.0625

The x term is -0.375x.  Take half its coefficient (-0.1875).
Square it (0.03515625) and add it to both sides.

Add '0.03515625' to each side of the equation.
-0.375x + 0.03515625 + x2 = -0.0625 + 0.03515625

Reorder the terms:
0.03515625 + -0.375x + x2 = -0.0625 + 0.03515625

Combine like terms: -0.0625 + 0.03515625 = -0.02734375
0.03515625 + -0.375x + x2 = -0.02734375

Factor a perfect square on the left side:
(x + -0.1875)(x + -0.1875) = -0.02734375
