=x^4+x^2

Solution for =x^4+x^2 equation:

Simplifying
0 = x4 + x2

Reorder the terms:
0 = x2 + x4

Solving
0 = x2 + x4

Solving for variable 'x'.
Remove the zero:
-1x2 + -1x4 = x2 + x4 + -1x2 + -1x4

Reorder the terms:
-1x2 + -1x4 = x2 + -1x2 + x4 + -1x4

Combine like terms: x2 + -1x2 = 0
-1x2 + -1x4 = 0 + x4 + -1x4
-1x2 + -1x4 = x4 + -1x4

Combine like terms: x4 + -1x4 = 0
-1x2 + -1x4 = 0

Factor out the Greatest Common Factor (GCF), '-1x2'.
-1x2(1 + x2) = 0

Ignore the factor -1.
Subproblem 1
Set the factor 'x2' equal to zero and attempt to solve:

Simplifying
x2 = 0

Solving
x2 = 0

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

Simplifying
x2 = 0

Take the square root of each side:
x = {0}
Subproblem 2
Set the factor '(1 + x2)' equal to zero and attempt to solve:

Simplifying
1 + x2 = 0

Solving
1 + x2 = 0

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

Add '-1' to each side of the equation.
1 + -1 + x2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + x2 = 0 + -1
x2 = 0 + -1

Combine like terms: 0 + -1 = -1
x2 = -1

Simplifying
x2 = -1
