Simplifying z7 + 2(z4) + z = 0 Reorder the terms: z + 2z4 + z7 = 0 Solving z + 2z4 + z7 = 0 Solving for variable 'z'. Factor out the Greatest Common Factor (GCF), 'z'. z(1 + 2z3 + z6) = 0 Factor a trinomial. z((1 + z3)(1 + z3)) = 0Subproblem 1
Set the factor 'z' equal to zero and attempt to solve: Simplifying z = 0 Solving z = 0 Move all terms containing z to the left, all other terms to the right. Simplifying z = 0Subproblem 2
Set the factor '(1 + z3)' equal to zero and attempt to solve: Simplifying 1 + z3 = 0 Solving 1 + z3 = 0 Move all terms containing z to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + z3 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + z3 = 0 + -1 z3 = 0 + -1 Combine like terms: 0 + -1 = -1 z3 = -1 Simplifying z3 = -1 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 3
