Subproblem 1
Set the factor '(-12 + 19x + -2x2)' equal to zero and attempt to solve:

Simplifying
-12 + 19x + -2x2 = 0

Solving
-12 + 19x + -2x2 = 0

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

Divide each side by '-2'.
6 + -9.5x + x2 = 0

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -9.5x + -6 + x2 = 0 + -6

Reorder the terms:
6 + -6 + -9.5x + x2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -9.5x + x2 = 0 + -6
-9.5x + x2 = 0 + -6

Combine like terms: 0 + -6 = -6
-9.5x + x2 = -6

The x term is -9.5x.  Take half its coefficient (-4.75).
Square it (22.5625) and add it to both sides.

Add '22.5625' to each side of the equation.
-9.5x + 22.5625 + x2 = -6 + 22.5625

Reorder the terms:
22.5625 + -9.5x + x2 = -6 + 22.5625

Combine like terms: -6 + 22.5625 = 16.5625
22.5625 + -9.5x + x2 = 16.5625

Factor a perfect square on the left side:
(x + -4.75)(x + -4.75) = 16.5625

Calculate the square root of the right side: 4.069705149
