Simplifying 0 = 12x5 + -20x3 Reorder the terms: 0 = -20x3 + 12x5 Solving 0 = -20x3 + 12x5 Solving for variable 'x'. Remove the zero: 20x3 + -12x5 = -20x3 + 12x5 + 20x3 + -12x5 Reorder the terms: 20x3 + -12x5 = -20x3 + 20x3 + 12x5 + -12x5 Combine like terms: -20x3 + 20x3 = 0 20x3 + -12x5 = 0 + 12x5 + -12x5 20x3 + -12x5 = 12x5 + -12x5 Combine like terms: 12x5 + -12x5 = 0 20x3 + -12x5 = 0 Factor out the Greatest Common Factor (GCF), '4x3'. 4x3(5 + -3x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor 'x3' equal to zero and attempt to solve: Simplifying x3 = 0 Solving x3 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x3 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(5 + -3x2)' equal to zero and attempt to solve: Simplifying 5 + -3x2 = 0 Solving 5 + -3x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -3x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -3x2 = 0 + -5 -3x2 = 0 + -5 Combine like terms: 0 + -5 = -5 -3x2 = -5 Divide each side by '-3'. x2 = 1.666666667 Simplifying x2 = 1.666666667 Take the square root of each side: x = {-1.290994449, 1.290994449}Solution
x = {-1.290994449, 1.290994449}
