Simplifying 7x(9x2 + 8) = 0 Reorder the terms: 7x(8 + 9x2) = 0 (8 * 7x + 9x2 * 7x) = 0 (56x + 63x3) = 0 Solving 56x + 63x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '7x'. 7x(8 + 9x2) = 0 Ignore the factor 7.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 '(8 + 9x2)' equal to zero and attempt to solve: Simplifying 8 + 9x2 = 0 Solving 8 + 9x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + 9x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 9x2 = 0 + -8 9x2 = 0 + -8 Combine like terms: 0 + -8 = -8 9x2 = -8 Divide each side by '9'. x2 = -0.8888888889 Simplifying x2 = -0.8888888889 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
