3h + h2 = 44

The h term is 3h.  Take half its coefficient (1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
3h + 2.25 + h2 = 44 + 2.25

Reorder the terms:
2.25 + 3h + h2 = 44 + 2.25

Combine like terms: 44 + 2.25 = 46.25
2.25 + 3h + h2 = 46.25

Factor a perfect square on the left side:
(h + 1.5)(h + 1.5) = 46.25
