-12lnx2 + 3x + xF = 12lnx2 + -12lnx2 + -3x + 3x

Combine like terms: 12lnx2 + -12lnx2 = 0
-12lnx2 + 3x + xF = 0 + -3x + 3x
-12lnx2 + 3x + xF = -3x + 3x

Combine like terms: -3x + 3x = 0
-12lnx2 + 3x + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-12lnx + 3 + F) = 0


Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:

Simplifying
x = 0

Solving
x = 0

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

Simplifying
x = 0

Subproblem 2
Set the factor '(-12lnx + 3 + F)' equal to zero and attempt to solve:

Simplifying
-12lnx + 3 + F = 0

Reorder the terms:
3 + F + -12lnx = 0

Solving
3 + F + -12lnx = 0

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

Add '-3' to each side of the equation.
3 + F + -3 + -12lnx = 0 + -3

Reorder the terms:
3 + -3 + F + -12lnx = 0 + -3

Combine like terms: 3 + -3 = 0
0 + F + -12lnx = 0 + -3
F + -12lnx = 0 + -3

Combine like terms: 0 + -3 = -3
F + -12lnx = -3

Add '-1F' to each side of the equation.
F + -1F + -12lnx = -3 + -1F

Combine like terms: F + -1F = 0
0 + -12lnx = -3 + -1F
-12lnx = -3 + -1F

Divide each side by '-12ln'.
x = 0.25l-1n-1 + 0.08333333333l-1n-1F

Simplifying
x = 0.25l-1n-1 + 0.08333333333l-1n-1F
Solution
x = {0, 0.25l-1n-1 + 0.08333333333l-1n-1F}
