Subproblem 2
Set the factor '(3X + 4sx + s2X)' equal to zero and attempt to solve:

Simplifying
3X + 4sx + s2X = 0

Solving
3X + 4sx + s2X = 0

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

Add '-3X' to each side of the equation.
3X + 4sx + -3X + s2X = 0 + -3X

Reorder the terms:
3X + -3X + 4sx + s2X = 0 + -3X

Combine like terms: 3X + -3X = 0
0 + 4sx + s2X = 0 + -3X
4sx + s2X = 0 + -3X
Remove the zero:
4sx + s2X = -3X

Add '-4sx' to each side of the equation.
4sx + -4sx + s2X = -3X + -4sx

Combine like terms: 4sx + -4sx = 0
0 + s2X = -3X + -4sx
s2X = -3X + -4sx

Add '-1s2X' to each side of the equation.
s2X + -1s2X = -3X + -4sx + -1s2X

Combine like terms: s2X + -1s2X = 0
0 = -3X + -4sx + -1s2X

Simplifying
0 = -3X + -4sx + -1s2X
