Simplifying
0 = (4x2 + -1) + (6x2 + x + 1)

Reorder the terms:
0 = (-1 + 4x2) + (6x2 + x + 1)

Remove parenthesis around (-1 + 4x2)
0 = -1 + 4x2 + (6x2 + x + 1)

Reorder the terms:
0 = -1 + 4x2 + (1 + x + 6x2)

Remove parenthesis around (1 + x + 6x2)
0 = -1 + 4x2 + 1 + x + 6x2

Reorder the terms:
0 = -1 + 1 + x + 4x2 + 6x2

Combine like terms: -1 + 1 = 0
0 = 0 + x + 4x2 + 6x2
0 = x + 4x2 + 6x2

Combine like terms: 4x2 + 6x2 = 10x2
0 = x + 10x2

Solving
0 = x + 10x2

Solving for variable 'x'.
Remove the zero:
-1x + -10x2 = x + 10x2 + -1x + -10x2

Reorder the terms:
-1x + -10x2 = x + -1x + 10x2 + -10x2

Combine like terms: x + -1x = 0
-1x + -10x2 = 0 + 10x2 + -10x2
-1x + -10x2 = 10x2 + -10x2

Combine like terms: 10x2 + -10x2 = 0
-1x + -10x2 = 0

Factor out the Greatest Common Factor (GCF), '-1x'.
-1x(1 + 10x) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(1 + 10x)' equal to zero and attempt to solve: Simplifying 1 + 10x = 0 Solving 1 + 10x = 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 + 10x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 10x = 0 + -1 10x = 0 + -1 Combine like terms: 0 + -1 = -1 10x = -1 Divide each side by '10'. x = -0.1 Simplifying x = -0.1

Solution

x = {0, -0.1}
