Subproblem 1
Set the factor '(11 + f)' equal to zero and attempt to solve:

Simplifying
11 + f = 0

Solving
11 + f = 0

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

Add '-11' to each side of the equation.
11 + -11 + f = 0 + -11

Combine like terms: 11 + -11 = 0
0 + f = 0 + -11
f = 0 + -11

Combine like terms: 0 + -11 = -11
f = -11

Simplifying
f = -11
Subproblem 2
Set the factor '(1 + f)' equal to zero and attempt to solve:

Simplifying
1 + f = 0

Solving
1 + f = 0

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

Add '-1' to each side of the equation.
1 + -1 + f = 0 + -1

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

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

Simplifying
f = -1
Solution
f = {-11, -1}
