Solving for variable 'k'.

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

Divide each side by '4'.
-24 + -0.25k + k2 = 0

Move the constant term to the right:

Add '24' to each side of the equation.
-24 + -0.25k + 24 + k2 = 0 + 24

Reorder the terms:
-24 + 24 + -0.25k + k2 = 0 + 24

Combine like terms: -24 + 24 = 0
0 + -0.25k + k2 = 0 + 24
-0.25k + k2 = 0 + 24

Combine like terms: 0 + 24 = 24
-0.25k + k2 = 24

The k term is -0.25k.  Take half its coefficient (-0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
-0.25k + 0.015625 + k2 = 24 + 0.015625

Reorder the terms:
0.015625 + -0.25k + k2 = 24 + 0.015625

Combine like terms: 24 + 0.015625 = 24.015625
0.015625 + -0.25k + k2 = 24.015625
