Solution for 10h^2+9h+20=0 equation:


Simplifying
10h2 + 9h + 20 = 0

Reorder the terms:
20 + 9h + 10h2 = 0

Solving
20 + 9h + 10h2 = 0

Solving for variable 'h'.

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

Divide each side by '10'.
2 + 0.9h + h2 = 0

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + 0.9h + -2 + h2 = 0 + -2

Reorder the terms:
2 + -2 + 0.9h + h2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 0.9h + h2 = 0 + -2
0.9h + h2 = 0 + -2

Combine like terms: 0 + -2 = -2
0.9h + h2 = -2

The h term is 0.9h.  Take half its coefficient (0.45).
Square it (0.2025) and add it to both sides.

Add '0.2025' to each side of the equation.
0.9h + 0.2025 + h2 = -2 + 0.2025

Reorder the terms:
0.2025 + 0.9h + h2 = -2 + 0.2025

Combine like terms: -2 + 0.2025 = -1.7975
0.2025 + 0.9h + h2 = -1.7975

Factor a perfect square on the left side:
(h + 0.45)(h + 0.45) = -1.7975

Can't calculate square root of the right side.

The solution to this equation could not be determined.
