Simplifying -3x2 + -40x = 0 Reorder the terms: -40x + -3x2 = 0 Solving -40x + -3x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-1x'. -1x(40 + 3x) = 0 Ignore the factor -1.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(40 + 3x)' equal to zero and attempt to solve: Simplifying 40 + 3x = 0 Solving 40 + 3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-40' to each side of the equation. 40 + -40 + 3x = 0 + -40 Combine like terms: 40 + -40 = 0 0 + 3x = 0 + -40 3x = 0 + -40 Combine like terms: 0 + -40 = -40 3x = -40 Divide each side by '3'. x = -13.33333333 Simplifying x = -13.33333333Solution
x = {0, -13.33333333}
