Simplifying 72x3 + 80x = 0 Reorder the terms: 80x + 72x3 = 0 Solving 80x + 72x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '8x'. 8x(10 + 9x2) = 0 Ignore the factor 8.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 '(10 + 9x2)' equal to zero and attempt to solve: Simplifying 10 + 9x2 = 0 Solving 10 + 9x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + 9x2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + 9x2 = 0 + -10 9x2 = 0 + -10 Combine like terms: 0 + -10 = -10 9x2 = -10 Divide each side by '9'. x2 = -1.111111111 Simplifying x2 = -1.111111111 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
