x = 0

Subproblem 2
Set the factor '(-4cos + F)' equal to zero and attempt to solve:

Simplifying
-4cos + F = 0

Reorder the terms:
F + -4cos = 0

Solving
F + -4cos = 0

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

Add '-1F' to each side of the equation.
F + -1F + -4cos = 0 + -1F

Combine like terms: F + -1F = 0
0 + -4cos = 0 + -1F
-4cos = 0 + -1F
Remove the zero:
-4cos = -1F

Add '4cos' to each side of the equation.
-4cos + 4cos = -1F + 4cos

Combine like terms: -4cos + 4cos = 0
0 = -1F + 4cos

Simplifying
0 = -1F + 4cos
