Simplifying (-4x9) * x(x8 + x) = 0 Remove parenthesis around (-4x9) -4x9 * x(x8 + x) = 0 Reorder the terms: -4x9 * x(x + x8) = 0 Multiply x9 * x -4x10(x + x8) = 0 (x * -4x10 + x8 * -4x10) = 0 (-4x11 + -4x18) = 0 Solving -4x11 + -4x18 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-4x11'. -4x11(1 + x7) = 0 Ignore the factor -4.Subproblem 1
Set the factor 'x11' equal to zero and attempt to solve: Simplifying x11 = 0 Solving x11 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x11 = 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 '(1 + x7)' equal to zero and attempt to solve: Simplifying 1 + x7 = 0 Solving 1 + x7 = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x7 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x7 = 0 + -1 x7 = 0 + -1 Combine like terms: 0 + -1 = -1 x7 = -1 Simplifying x7 = -1 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
