5 the coefficient of the squared term: 

Divide each side by '5'.
1.8 + -0.9x + x2 = 0.0

Move the constant term to the right:

Add '-1.8' to each side of the equation.
1.8 + -0.9x + -1.8 + x2 = 0.0 + -1.8

Reorder the terms:
1.8 + -1.8 + -0.9x + x2 = 0.0 + -1.8

Combine like terms: 1.8 + -1.8 = 0.0
0.0 + -0.9x + x2 = 0.0 + -1.8
-0.9x + x2 = 0.0 + -1.8

Combine like terms: 0.0 + -1.8 = -1.8
-0.9x + x2 = -1.8

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 = -1.8 + 0.2025

Reorder the terms:
0.2025 + -0.9x + x2 = -1.8 + 0.2025

Combine like terms: -1.8 + 0.2025 = -1.5975
0.2025 + -0.9x + x2 = -1.5975

Factor a perfect square on the left side:
(x + -0.45)(x + -0.45) = -1.5975

Can't calculate square root of the right side.
