Subproblem 1
Set the factor '(1 + 3x + -2x2)' equal to zero and attempt to solve:

Simplifying
1 + 3x + -2x2 = 0

Solving
1 + 3x + -2x2 = 0

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
-0.5 + -1.5x + x2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + -1.5x + 0.5 + x2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + -1.5x + x2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + -1.5x + x2 = 0 + 0.5
-1.5x + x2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
-1.5x + x2 = 0.5

The x term is -1.5x.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5x + 0.5625 + x2 = 0.5 + 0.5625

Reorder the terms:
0.5625 + -1.5x + x2 = 0.5 + 0.5625

Combine like terms: 0.5 + 0.5625 = 1.0625
0.5625 + -1.5x + x2 = 1.0625

Factor a perfect square on the left side:
(x + -0.75)(x + -0.75) = 1.0625

Calculate the square root of the right side: 1.030776406

Break this problem into two subproblems by setting 
(x + -0.75) equal to 1.030776406 and -1.030776406.

Subproblem 1
x + -0.75 = 1.030776406

Simplifying
x + -0.75 = 1.030776406

Reorder the terms:
-0.75 + x = 1.030776406

Solving
-0.75 + x = 1.030776406

Solving for variable 'x'.

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

Add '0.75' to each side of the equation.
-0.75 + 0.75 + x = 1.030776406 + 0.75

Combine like terms: -0.75 + 0.75 = 0.00
0.00 + x = 1.030776406 + 0.75
x = 1.030776406 + 0.75

Combine like terms: 1.030776406 + 0.75 = 1.780776406
x = 1.780776406

Simplifying
x = 1.780776406

Subproblem 2
x + -0.75 = -1.030776406

Simplifying
x + -0.75 = -1.030776406

Reorder the terms:
-0.75 + x = -1.030776406

Solving
-0.75 + x = -1.030776406

Solving for variable 'x'.

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

Add '0.75' to each side of the equation.
-0.75 + 0.75 + x = -1.030776406 + 0.75

Combine like terms: -0.75 + 0.75 = 0.00
0.00 + x = -1.030776406 + 0.75
x = -1.030776406 + 0.75
