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

Divide each side by '5'.
-5 + -0.6h + h2 = 0

Move the constant term to the right:

Add '5' to each side of the equation.
-5 + -0.6h + 5 + h2 = 0 + 5

Reorder the terms:
-5 + 5 + -0.6h + h2 = 0 + 5

Combine like terms: -5 + 5 = 0
0 + -0.6h + h2 = 0 + 5
-0.6h + h2 = 0 + 5

Combine like terms: 0 + 5 = 5
-0.6h + h2 = 5

The h term is -0.6h.  Take half its coefficient (-0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
-0.6h + 0.09 + h2 = 5 + 0.09

Reorder the terms:
0.09 + -0.6h + h2 = 5 + 0.09

Combine like terms: 5 + 0.09 = 5.09
0.09 + -0.6h + h2 = 5.09
