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

Simplifying
3 + 2x + 2x2 = 0

Solving
3 + 2x + 2x2 = 0

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

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

Move the constant term to the right:

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

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

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

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

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + x2 = -1.5 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + x2 = -1.5 + 0.25

Combine like terms: -1.5 + 0.25 = -1.25
1.25 + x2 = -1.25

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -1.25

Can't calculate square root of the right side.
