Subproblem 2
Set the factor '(3 + f)' equal to zero and attempt to solve:

Simplifying
3 + f = 0

Solving
3 + f = 0

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

Add '-3' to each side of the equation.
3 + -3 + f = 0 + -3

Combine like terms: 3 + -3 = 0
0 + f = 0 + -3
f = 0 + -3

Combine like terms: 0 + -3 = -3
f = -3

Add '-1f' to each side of the equation.
f + -1f = -3 + -1f

Combine like terms: f + -1f = 0
0 = -3 + -1f

Simplifying
0 = -3 + -1f
