Simplifying 0 = 20x + -50x2 Solving 0 = 20x + -50x2 Solving for variable 'x'. Remove the zero: -20x + 50x2 = 20x + -50x2 + -20x + 50x2 Reorder the terms: -20x + 50x2 = 20x + -20x + -50x2 + 50x2 Combine like terms: 20x + -20x = 0 -20x + 50x2 = 0 + -50x2 + 50x2 -20x + 50x2 = -50x2 + 50x2 Combine like terms: -50x2 + 50x2 = 0 -20x + 50x2 = 0 Factor out the Greatest Common Factor (GCF), '10x'. 10x(-2 + 5x) = 0 Ignore the factor 10.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 '(-2 + 5x)' equal to zero and attempt to solve: Simplifying -2 + 5x = 0 Solving -2 + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + 5x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 5x = 0 + 2 5x = 0 + 2 Combine like terms: 0 + 2 = 2 5x = 2 Divide each side by '5'. x = 0.4 Simplifying x = 0.4Solution
x = {0, 0.4}
