Simplifying x3 = 3x3 + -4x Reorder the terms: x3 = -4x + 3x3 Solving x3 = -4x + 3x3 Solving for variable 'x'. Reorder the terms: 4x + x3 + -3x3 = -4x + 3x3 + 4x + -3x3 Combine like terms: x3 + -3x3 = -2x3 4x + -2x3 = -4x + 3x3 + 4x + -3x3 Reorder the terms: 4x + -2x3 = -4x + 4x + 3x3 + -3x3 Combine like terms: -4x + 4x = 0 4x + -2x3 = 0 + 3x3 + -3x3 4x + -2x3 = 3x3 + -3x3 Combine like terms: 3x3 + -3x3 = 0 4x + -2x3 = 0 Factor out the Greatest Common Factor (GCF), '2x'. 2x(2 + -1x2) = 0 Ignore the factor 2.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 = 0Subproblem 2
Set the factor '(2 + -1x2)' equal to zero and attempt to solve: Simplifying 2 + -1x2 = 0 Solving 2 + -1x2 = 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 + -1x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x2 = 0 + -2 -1x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -1x2 = -2 Divide each side by '-1'. x2 = 2 Simplifying x2 = 2 Take the square root of each side: x = {-1.414213562, 1.414213562}Solution
x = {0, -1.414213562, 1.414213562}
