f(x+4)=

Solution for f(x+4)= equation:

Simplifying
f(x + 4) = 0

Reorder the terms:
f(4 + x) = 0
(4 * f + x * f) = 0
(4f + fx) = 0

Solving
4f + fx = 0

Solving for variable 'f'.

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

Factor out the Greatest Common Factor (GCF), 'f'.
f(4 + x) = 0

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

Simplifying
f = 0

Solving
f = 0

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

Simplifying
f = 0
Subproblem 2
Set the factor '(4 + x)' equal to zero and attempt to solve:

Simplifying
4 + x = 0

Solving
4 + x = 0

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

Add '-4' to each side of the equation.
4 + -4 + x = 0 + -4

Combine like terms: 4 + -4 = 0
0 + x = 0 + -4
x = 0 + -4

Combine like terms: 0 + -4 = -4
x = -4

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

Combine like terms: x + -1x = 0
0 = -4 + -1x

Simplifying
0 = -4 + -1x
