-.5*32h^2+16h+0=2.56

Solution for -.5*32h^2+16h+0=2.56 equation:

Simplifying
-0.5 * 32h2 + 16h + 0 = 2.56

Multiply -0.5 * 32
-16h2 + 16h + 0 = 2.56

Reorder the terms:
0 + 16h + -16h2 = 2.56
Remove the zero:
16h + -16h2 = 2.56

Solving
16h + -16h2 = 2.56

Solving for variable 'h'.

Reorder the terms:
-2.56 + 16h + -16h2 = 2.56 + -2.56

Combine like terms: 2.56 + -2.56 = 0.00
-2.56 + 16h + -16h2 = 0.00

Begin completing the square.  Divide all terms by
-16 the coefficient of the squared term: 

Divide each side by '-16'.
0.16 + -1h + h2 = 0.00

Move the constant term to the right:

Add '-0.16' to each side of the equation.
0.16 + -1h + -0.16 + h2 = 0.00 + -0.16

Reorder the terms:
0.16 + -0.16 + -1h + h2 = 0.00 + -0.16

Combine like terms: 0.16 + -0.16 = 0.00
0.00 + -1h + h2 = 0.00 + -0.16
-1h + h2 = 0.00 + -0.16

Combine like terms: 0.00 + -0.16 = -0.16
-1h + h2 = -0.16

The h term is -1h.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1h + 0.25 + h2 = -0.16 + 0.25

Reorder the terms:
0.25 + -1h + h2 = -0.16 + 0.25

Combine like terms: -0.16 + 0.25 = 0.09
0.25 + -1h + h2 = 0.09

Factor a perfect square on the left side:
(h + -0.5)(h + -0.5) = 0.09

Calculate the square root of the right side: 0.3

Break this problem into two subproblems by setting 
(h + -0.5) equal to 0.3 and -0.3.

Subproblem 1
h + -0.5 = 0.3

Simplifying
h + -0.5 = 0.3

Reorder the terms:
-0.5 + h = 0.3

Solving
-0.5 + h = 0.3

Solving for variable 'h'.

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

Add '0.5' to each side of the equation.
-0.5 + 0.5 + h = 0.3 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + h = 0.3 + 0.5
h = 0.3 + 0.5

Combine like terms: 0.3 + 0.5 = 0.8
h = 0.8

Simplifying
h = 0.8

Subproblem 2
h + -0.5 = -0.3

Simplifying
h + -0.5 = -0.3

Reorder the terms:
-0.5 + h = -0.3

Solving
-0.5 + h = -0.3

Solving for variable 'h'.

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

Add '0.5' to each side of the equation.
-0.5 + 0.5 + h = -0.3 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + h = -0.3 + 0.5
h = -0.3 + 0.5

Combine like terms: -0.3 + 0.5 = 0.2
h = 0.2

Simplifying
h = 0.2

Solution
The solution to the problem is based on the solutions
from the subproblems.
h = {0.8, 0.2}
