Subproblem 2
Set the factor '(6 + 3x + 4x2)' equal to zero and attempt to solve:

Simplifying
6 + 3x + 4x2 = 0

Solving
6 + 3x + 4x2 = 0

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

Divide each side by '4'.
1.5 + 0.75x + x2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + 0.75x + -1.5 + x2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + 0.75x + x2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + 0.75x + x2 = 0 + -1.5
0.75x + x2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
0.75x + x2 = -1.5

The x term is 0.75x.  Take half its coefficient (0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
0.75x + 0.140625 + x2 = -1.5 + 0.140625

Reorder the terms:
0.140625 + 0.75x + x2 = -1.5 + 0.140625

Combine like terms: -1.5 + 0.140625 = -1.359375
0.140625 + 0.75x + x2 = -1.359375

Factor a perfect square on the left side:
(x + 0.375)(x + 0.375) = -1.359375

Can't calculate square root of the right side.
