4 + -1k + 8k2 = 0

Solving for variable 'k'.

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

Divide each side by '8'.
0.5 + -0.125k + k2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -0.125k + -0.5 + k2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -0.125k + k2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -0.125k + k2 = 0 + -0.5
-0.125k + k2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-0.125k + k2 = -0.5

The k term is -0.125k.  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.
-0.125k + 0.00390625 + k2 = -0.5 + 0.00390625

Reorder the terms:
0.00390625 + -0.125k + k2 = -0.5 + 0.00390625

Combine like terms: -0.5 + 0.00390625 = -0.49609375
0.00390625 + -0.125k + k2 = -0.49609375
