Solving for variable 'k'.

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

Divide each side by '8'.
0.125 + -1.5k + k2 = 0

Move the constant term to the right:

Add '-0.125' to each side of the equation.
0.125 + -1.5k + -0.125 + k2 = 0 + -0.125

Reorder the terms:
0.125 + -0.125 + -1.5k + k2 = 0 + -0.125

Combine like terms: 0.125 + -0.125 = 0.000
0.000 + -1.5k + k2 = 0 + -0.125
-1.5k + k2 = 0 + -0.125

Combine like terms: 0 + -0.125 = -0.125
-1.5k + k2 = -0.125

The k term is -1.5k.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5k + 0.5625 + k2 = -0.125 + 0.5625

Reorder the terms:
0.5625 + -1.5k + k2 = -0.125 + 0.5625

Combine like terms: -0.125 + 0.5625 = 0.4375
0.5625 + -1.5k + k2 = 0.4375

Factor a perfect square on the left side:
(k + -0.75)(k + -0.75) = 0.4375

Calculate the square root of the right side: 0.661437828

Break this problem into two subproblems by setting 
(k + -0.75) equal to 0.661437828 and -0.661437828.
