Reorder the terms:
-9 + 13x + -5x2 = -10x + 10x + 5x2 + -5x2

Combine like terms: -10x + 10x = 0
-9 + 13x + -5x2 = 0 + 5x2 + -5x2
-9 + 13x + -5x2 = 5x2 + -5x2

Combine like terms: 5x2 + -5x2 = 0
-9 + 13x + -5x2 = 0

Begin completing the square.  Divide all terms by
-5 the coefficient of the squared term: 

Divide each side by '-5'.
1.8 + -2.6x + x2 = 0

Move the constant term to the right:

Add '-1.8' to each side of the equation.
1.8 + -2.6x + -1.8 + x2 = 0 + -1.8

Reorder the terms:
1.8 + -1.8 + -2.6x + x2 = 0 + -1.8

Combine like terms: 1.8 + -1.8 = 0.0
0.0 + -2.6x + x2 = 0 + -1.8
-2.6x + x2 = 0 + -1.8

Combine like terms: 0 + -1.8 = -1.8
-2.6x + x2 = -1.8

The x term is -2.6x.  Take half its coefficient (-1.3).
Square it (1.69) and add it to both sides.

Add '1.69' to each side of the equation.
-2.6x + 1.69 + x2 = -1.8 + 1.69

Reorder the terms:
1.69 + -2.6x + x2 = -1.8 + 1.69

Combine like terms: -1.8 + 1.69 = -0.11
1.69 + -2.6x + x2 = -0.11

Factor a perfect square on the left side:
(x + -1.3)(x + -1.3) = -0.11

Can't calculate square root of the right side.
