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

Divide each side by '2'.
-0.5 + -2.5h + h2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + -2.5h + 0.5 + h2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + -2.5h + h2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + -2.5h + h2 = 0 + 0.5
-2.5h + h2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
-2.5h + h2 = 0.5

The h term is -2.5h.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5h + 1.5625 + h2 = 0.5 + 1.5625

Reorder the terms:
1.5625 + -2.5h + h2 = 0.5 + 1.5625

Combine like terms: 0.5 + 1.5625 = 2.0625
1.5625 + -2.5h + h2 = 2.0625

Factor a perfect square on the left side:
(h + -1.25)(h + -1.25) = 2.0625

Calculate the square root of the right side: 1.436140662

Break this problem into two subproblems by setting 
(h + -1.25) equal to 1.436140662 and -1.436140662.

Subproblem 1
h + -1.25 = 1.436140662

Simplifying
h + -1.25 = 1.436140662

Reorder the terms:
-1.25 + h = 1.436140662

Solving
-1.25 + h = 1.436140662

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Add '1.25' to each side of the equation.
-1.25 + 1.25 + h = 1.436140662 + 1.25

Combine like terms: -1.25 + 1.25 = 0.00
0.00 + h = 1.436140662 + 1.25
h = 1.436140662 + 1.25

Combine like terms: 1.436140662 + 1.25 = 2.686140662
h = 2.686140662

Simplifying
h = 2.686140662

Subproblem 2
h + -1.25 = -1.436140662

Simplifying
h + -1.25 = -1.436140662

Reorder the terms:
-1.25 + h = -1.436140662

Solving
-1.25 + h = -1.436140662

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Add '1.25' to each side of the equation.
-1.25 + 1.25 + h = -1.436140662 + 1.25

Combine like terms: -1.25 + 1.25 = 0.00
0.00 + h = -1.436140662 + 1.25
h = -1.436140662 + 1.25

Combine like terms: -1.436140662 + 1.25 = -0.186140662
h = -0.186140662

Simplifying
h = -0.186140662
