Simplifying -20x2 = 36x Solving -20x2 = 36x Solving for variable 'x'. Reorder the terms: -36x + -20x2 = 36x + -36x Combine like terms: 36x + -36x = 0 -36x + -20x2 = 0 Factor out the Greatest Common Factor (GCF), '-4x'. -4x(9 + 5x) = 0 Ignore the factor -4.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 '(9 + 5x)' equal to zero and attempt to solve: Simplifying 9 + 5x = 0 Solving 9 + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + 5x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 5x = 0 + -9 5x = 0 + -9 Combine like terms: 0 + -9 = -9 5x = -9 Divide each side by '5'. x = -1.8 Simplifying x = -1.8Solution
x = {0, -1.8}
