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

Divide each side by '4'.
-8.75 + 0.5h + h2 = 0

Move the constant term to the right:

Add '8.75' to each side of the equation.
-8.75 + 0.5h + 8.75 + h2 = 0 + 8.75

Reorder the terms:
-8.75 + 8.75 + 0.5h + h2 = 0 + 8.75

Combine like terms: -8.75 + 8.75 = 0.00
0.00 + 0.5h + h2 = 0 + 8.75
0.5h + h2 = 0 + 8.75

Combine like terms: 0 + 8.75 = 8.75
0.5h + h2 = 8.75

The h term is 0.5h.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5h + 0.0625 + h2 = 8.75 + 0.0625

Reorder the terms:
0.0625 + 0.5h + h2 = 8.75 + 0.0625

Combine like terms: 8.75 + 0.0625 = 8.8125
0.0625 + 0.5h + h2 = 8.8125

Factor a perfect square on the left side:
(h + 0.25)(h + 0.25) = 8.8125
