Solving for variable 'h'.

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

Divide each side by '2'.
-15 + 12.5h + h2 = 0

Move the constant term to the right:

Add '15' to each side of the equation.
-15 + 12.5h + 15 + h2 = 0 + 15

Reorder the terms:
-15 + 15 + 12.5h + h2 = 0 + 15

Combine like terms: -15 + 15 = 0
0 + 12.5h + h2 = 0 + 15
12.5h + h2 = 0 + 15

Combine like terms: 0 + 15 = 15
12.5h + h2 = 15

The h term is 12.5h.  Take half its coefficient (6.25).
Square it (39.0625) and add it to both sides.

Add '39.0625' to each side of the equation.
12.5h + 39.0625 + h2 = 15 + 39.0625

Reorder the terms:
39.0625 + 12.5h + h2 = 15 + 39.0625

Combine like terms: 15 + 39.0625 = 54.0625
39.0625 + 12.5h + h2 = 54.0625
