Solving for variable 'k'.

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

Divide each side by '5'.
-5.8 + -2.6k + k2 = 0

Move the constant term to the right:

Add '5.8' to each side of the equation.
-5.8 + -2.6k + 5.8 + k2 = 0 + 5.8

Reorder the terms:
-5.8 + 5.8 + -2.6k + k2 = 0 + 5.8

Combine like terms: -5.8 + 5.8 = 0.0
0.0 + -2.6k + k2 = 0 + 5.8
-2.6k + k2 = 0 + 5.8

Combine like terms: 0 + 5.8 = 5.8
-2.6k + k2 = 5.8

The k term is -2.6k.  Take half its coefficient (-1.3).
Square it (1.69) and add it to both sides.

Add '1.69' to each side of the equation.
-2.6k + 1.69 + k2 = 5.8 + 1.69

Reorder the terms:
1.69 + -2.6k + k2 = 5.8 + 1.69

Combine like terms: 5.8 + 1.69 = 7.49
1.69 + -2.6k + k2 = 7.49

Factor a perfect square on the left side:
(k + -1.3)(k + -1.3) = 7.49

Calculate the square root of the right side: 2.736786437
