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.

Take the square root of each side:
X = {0}
Subproblem 2
Set the factor '(1 + X2 + X4)' equal to zero and attempt to solve:

Simplifying
1 + X2 + X4 = 0

Solving
1 + X2 + X4 = 0

Begin completing the square.

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + X2 + -1 + X4 = 0 + -1

Reorder the terms:
1 + -1 + X2 + X4 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + X2 + X4 = 0 + -1
X2 + X4 = 0 + -1

Combine like terms: 0 + -1 = -1
X2 + X4 = -1

The X term is X2.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
X2 + 0.25 + X4 = -1 + 0.25

Reorder the terms:
0.25 + X2 + X4 = -1 + 0.25

Combine like terms: -1 + 0.25 = -0.75
0.25 + X2 + X4 = -0.75

Factor a perfect square on the left side:
(X2 + 0.5)(X2 + 0.5) = -0.75

Can't calculate square root of the right side.
