h-h^2=6

Solution for h-h^2=6 equation:

Simplifying
h + -1h2 = 6

Solving
h + -1h2 = 6

Solving for variable 'h'.

Reorder the terms:
-6 + h + -1h2 = 6 + -6

Combine like terms: 6 + -6 = 0
-6 + h + -1h2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
6 + -1h + h2 = 0

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -1h + -6 + h2 = 0 + -6

Reorder the terms:
6 + -6 + -1h + h2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1h + h2 = 0 + -6
-1h + h2 = 0 + -6

Combine like terms: 0 + -6 = -6
-1h + h2 = -6

The h term is h.  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 = -6 + 0.25

Reorder the terms:
0.25 + -1h + h2 = -6 + 0.25

Combine like terms: -6 + 0.25 = -5.75
0.25 + -1h + h2 = -5.75

Factor a perfect square on the left side:
(h + 0.5)(h + 0.5) = -5.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
