Solving for variable 'x'.

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

Divide each side by '-10'.
-2.4 + 0.9x + x2 = 0

Move the constant term to the right:

Add '2.4' to each side of the equation.
-2.4 + 0.9x + 2.4 + x2 = 0 + 2.4

Reorder the terms:
-2.4 + 2.4 + 0.9x + x2 = 0 + 2.4

Combine like terms: -2.4 + 2.4 = 0.0
0.0 + 0.9x + x2 = 0 + 2.4
0.9x + x2 = 0 + 2.4

Combine like terms: 0 + 2.4 = 2.4
0.9x + x2 = 2.4

The x term is 0.9x.  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.
0.9x + 0.2025 + x2 = 2.4 + 0.2025

Reorder the terms:
0.2025 + 0.9x + x2 = 2.4 + 0.2025

Combine like terms: 2.4 + 0.2025 = 2.6025
0.2025 + 0.9x + x2 = 2.6025

Factor a perfect square on the left side:
(x + 0.45)(x + 0.45) = 2.6025

Calculate the square root of the right side: 1.61322658
