Begin completing the square.

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + -4h + -1 + h2 = 0 + -1

Reorder the terms:
1 + -1 + -4h + h2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -4h + h2 = 0 + -1
-4h + h2 = 0 + -1

Combine like terms: 0 + -1 = -1
-4h + h2 = -1

The h term is -4h.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4h + 4 + h2 = -1 + 4

Reorder the terms:
4 + -4h + h2 = -1 + 4

Combine like terms: -1 + 4 = 3
4 + -4h + h2 = 3

Factor a perfect square on the left side:
(h + -2)(h + -2) = 3

Calculate the square root of the right side: 1.732050808

Break this problem into two subproblems by setting 
(h + -2) equal to 1.732050808 and -1.732050808.

Subproblem 1
h + -2 = 1.732050808

Simplifying
h + -2 = 1.732050808

Reorder the terms:
-2 + h = 1.732050808

Solving
-2 + h = 1.732050808

Solving for variable 'h'.

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

Add '2' to each side of the equation.
-2 + 2 + h = 1.732050808 + 2

Combine like terms: -2 + 2 = 0
0 + h = 1.732050808 + 2
h = 1.732050808 + 2

Combine like terms: 1.732050808 + 2 = 3.732050808
h = 3.732050808

Simplifying
h = 3.732050808

Subproblem 2
h + -2 = -1.732050808

Simplifying
h + -2 = -1.732050808

Reorder the terms:
-2 + h = -1.732050808

Solving
-2 + h = -1.732050808

Solving for variable 'h'.

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

Add '2' to each side of the equation.
-2 + 2 + h = -1.732050808 + 2

Combine like terms: -2 + 2 = 0
0 + h = -1.732050808 + 2
h = -1.732050808 + 2

Combine like terms: -1.732050808 + 2 = 0.267949192
h = 0.267949192

Simplifying
h = 0.267949192

Solution
The solution to the problem is based on the solutions
from the subproblems.
h = {3.732050808, 0.267949192}
