Simplifying -5z2 + -10z = 0 Reorder the terms: -10z + -5z2 = 0 Solving -10z + -5z2 = 0 Solving for variable 'z'. Factor out the Greatest Common Factor (GCF), '-5z'. -5z(2 + z) = 0 Ignore the factor -5.Subproblem 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 '(2 + z)' equal to zero and attempt to solve: Simplifying 2 + z = 0 Solving 2 + z = 0 Move all terms containing z to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + z = 0 + -2 Combine like terms: 2 + -2 = 0 0 + z = 0 + -2 z = 0 + -2 Combine like terms: 0 + -2 = -2 z = -2 Simplifying z = -2Solution
z = {0, -2}
