Simplifying 3n(7n + -2) = 0 Reorder the terms: 3n(-2 + 7n) = 0 (-2 * 3n + 7n * 3n) = 0 (-6n + 21n2) = 0 Solving -6n + 21n2 = 0 Solving for variable 'n'. Factor out the Greatest Common Factor (GCF), '3n'. 3n(-2 + 7n) = 0 Ignore the factor 3.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 '(-2 + 7n)' equal to zero and attempt to solve: Simplifying -2 + 7n = 0 Solving -2 + 7n = 0 Move all terms containing n to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + 7n = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 7n = 0 + 2 7n = 0 + 2 Combine like terms: 0 + 2 = 2 7n = 2 Divide each side by '7'. n = 0.2857142857 Simplifying n = 0.2857142857Solution
n = {0, 0.2857142857}
