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

Divide each side by '0.5'.
-1.36 + -3x + x2 = 0

Move the constant term to the right:

Add '1.36' to each side of the equation.
-1.36 + -3x + 1.36 + x2 = 0 + 1.36

Reorder the terms:
-1.36 + 1.36 + -3x + x2 = 0 + 1.36

Combine like terms: -1.36 + 1.36 = 0.00
0.00 + -3x + x2 = 0 + 1.36
-3x + x2 = 0 + 1.36

Combine like terms: 0 + 1.36 = 1.36
-3x + x2 = 1.36

The x term is -3x.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3x + 2.25 + x2 = 1.36 + 2.25

Reorder the terms:
2.25 + -3x + x2 = 1.36 + 2.25

Combine like terms: 1.36 + 2.25 = 3.61
2.25 + -3x + x2 = 3.61

Factor a perfect square on the left side:
(x + -1.5)(x + -1.5) = 3.61

Calculate the square root of the right side: 1.9

Break this problem into two subproblems by setting 
(x + -1.5) equal to 1.9 and -1.9.


Subproblem 1
x + -1.5 = 1.9

Simplifying
x + -1.5 = 1.9

Reorder the terms:
-1.5 + x = 1.9

Solving
-1.5 + x = 1.9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1.5' to each side of the equation.
-1.5 + 1.5 + x = 1.9 + 1.5

Combine like terms: -1.5 + 1.5 = 0.0
0.0 + x = 1.9 + 1.5
x = 1.9 + 1.5

Combine like terms: 1.9 + 1.5 = 3.4
x = 3.4

Simplifying
x = 3.4


Subproblem 2
x + -1.5 = -1.9

Simplifying
x + -1.5 = -1.9

Reorder the terms:
-1.5 + x = -1.9

Solving
-1.5 + x = -1.9

Solving for variable 'x'.
