Simplifying z7 + -18z5 = 0 Reorder the terms: -18z5 + z7 = 0 Solving -18z5 + z7 = 0 Solving for variable 'z'. Factor out the Greatest Common Factor (GCF), 'z5'. z5(-18 + z2) = 0Subproblem 1
Set the factor 'z5' equal to zero and attempt to solve: Simplifying z5 = 0 Solving z5 = 0 Move all terms containing z to the left, all other terms to the right. Simplifying z5 = 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 '(-18 + z2)' equal to zero and attempt to solve: Simplifying -18 + z2 = 0 Solving -18 + z2 = 0 Move all terms containing z to the left, all other terms to the right. Add '18' to each side of the equation. -18 + 18 + z2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + z2 = 0 + 18 z2 = 0 + 18 Combine like terms: 0 + 18 = 18 z2 = 18 Simplifying z2 = 18 Take the square root of each side: z = {-4.242640687, 4.242640687}Solution
z = {-4.242640687, 4.242640687}
