x = 9x2 + 4x

Reorder the terms:
x = 4x + 9x2

Solving
x = 4x + 9x2

Solving for variable 'x'.

Combine like terms: x + -4x = -3x
-3x + -9x2 = 4x + 9x2 + -4x + -9x2

Reorder the terms:
-3x + -9x2 = 4x + -4x + 9x2 + -9x2

Combine like terms: 4x + -4x = 0
-3x + -9x2 = 0 + 9x2 + -9x2
-3x + -9x2 = 9x2 + -9x2

Combine like terms: 9x2 + -9x2 = 0
-3x + -9x2 = 0

Factor out the Greatest Common Factor (GCF), '-3x'.
-3x(1 + 3x) = 0

Ignore the factor -3.

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 + 3x)' equal to zero and attempt to solve: Simplifying 1 + 3x = 0 Solving 1 + 3x = 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 + 3x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 3x = 0 + -1 3x = 0 + -1 Combine like terms: 0 + -1 = -1 3x = -1 Divide each side by '3'. x = -0.3333333333 Simplifying x = -0.3333333333

Solution

x = {0, -0.3333333333}
