Simplifying -20n2 + -36n = 0 Reorder the terms: -36n + -20n2 = 0 Solving -36n + -20n2 = 0 Solving for variable 'n'. Factor out the Greatest Common Factor (GCF), '-4n'. -4n(9 + 5n) = 0 Ignore the factor -4.Subproblem 1
Set the factor 'n' equal to zero and attempt to solve: Simplifying n = 0 Solving n = 0 Move all terms containing n to the left, all other terms to the right. Simplifying n = 0Subproblem 2
Set the factor '(9 + 5n)' equal to zero and attempt to solve: Simplifying 9 + 5n = 0 Solving 9 + 5n = 0 Move all terms containing n to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + 5n = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 5n = 0 + -9 5n = 0 + -9 Combine like terms: 0 + -9 = -9 5n = -9 Divide each side by '5'. n = -1.8 Simplifying n = -1.8Solution
n = {0, -1.8}
