<span>Simplifying
x4 = 16
 Solving
x4 = 16
 Solving for variable 'x'.
  Move all terms containing x to the left, all other terms to the right.
Simplifying
x4 = 16
 Reorder the terms:
-16 + x4 = 16 + -16
 Combine like terms: 16 + -16 = 0
-16 + x4 = 0
 Factor a difference between two squares.
(4 + x2)(-4 + x2) = 0
 Factor a difference between two squares.
(4 + x2)((2 + x)(-2 + x)) = 0
Subproblem 1
Set the factor '(4 + x2)' equal to zero and attempt to solve:
 Simplifying
4 + x2 = 0
Solving
4 + x2 = 0
 Move all terms containing x to the left, all other terms to the right.
 Add '-4' to each side of the equation.
4 + -4 + x2 = 0 + -4
 Combine like terms: 4 + -4 = 0
0 + x2 = 0 + -4
x2 = 0 + -4
 Combine like terms: 0 + -4 = -4
x2 = -4
 Simplifying
x2 = -4
The solution to this equation could not be determined.
 This subproblem is being ignored because a solution could not be determined.
Subproblem 2
Set the factor '(2 + x)' equal to zero and attempt to solve:
 Simplifying
2 + x = 0
Solving
2 + x = 0
 Move all terms containing x to the left, all other terms to the right.
 Add '-2' to each side of the equation.
2 + -2 + x = 0 + -2
Combine like terms: 2 + -2 = 0
0 + x = 0 + -2
x = 0 + -2
 Combine like terms: 0 + -2 = -2
x = -2
Simplifying
x = -2
Sub-problem 3
Set the factor '(-2 + x)' equal to zero and attempt to solve:
 Simplifying
-2 + x = 0
Solving
-2 + x = 0
 Move all terms containing x to the left, all other terms to the right.
 Add '2' to each side of the equation.
-2 + 2 + x = 0 + 2
 Combine like terms: -2 + 2 = 0
0 + x = 0 + 2
x = 0 + 2
 Combine like terms: 0 + 2 = 2
x = 2
Simplifying
x = 2Solutionx = {-2, 2}</span>
