Solving for variable 'n'.

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

Divide each side by '-10'.
-2.4 + -0.9n + n2 = 0

Move the constant term to the right:

Add '2.4' to each side of the equation.
-2.4 + -0.9n + 2.4 + n2 = 0 + 2.4

Reorder the terms:
-2.4 + 2.4 + -0.9n + n2 = 0 + 2.4

Combine like terms: -2.4 + 2.4 = 0.0
0.0 + -0.9n + n2 = 0 + 2.4
-0.9n + n2 = 0 + 2.4

Combine like terms: 0 + 2.4 = 2.4
-0.9n + n2 = 2.4

The n term is -0.9n.  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.
-0.9n + 0.2025 + n2 = 2.4 + 0.2025

Reorder the terms:
0.2025 + -0.9n + n2 = 2.4 + 0.2025

Combine like terms: 2.4 + 0.2025 = 2.6025
0.2025 + -0.9n + n2 = 2.6025

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