Simplifying -7x(x2 + 5) = 0 Reorder the terms: -7x(5 + x2) = 0 (5 * -7x + x2 * -7x) = 0 (-35x + -7x3) = 0 Solving -35x + -7x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-7x'. -7x(5 + x2) = 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 '(5 + x2)' equal to zero and attempt to solve: Simplifying 5 + x2 = 0 Solving 5 + x2 = 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 + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + x2 = 0 + -5 x2 = 0 + -5 Combine like terms: 0 + -5 = -5 x2 = -5 Simplifying x2 = -5 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
