Simplifying 0 = (2x + -5) * x Reorder the terms: 0 = (-5 + 2x) * x Reorder the terms for easier multiplication: 0 = x(-5 + 2x) 0 = (-5 * x + 2x * x) 0 = (-5x + 2x2) Solving 0 = -5x + 2x2 Solving for variable 'x'. Remove the zero: 5x + -2x2 = -5x + 2x2 + 5x + -2x2 Reorder the terms: 5x + -2x2 = -5x + 5x + 2x2 + -2x2 Combine like terms: -5x + 5x = 0 5x + -2x2 = 0 + 2x2 + -2x2 5x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 5x + -2x2 = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(5 + -2x) = 0Subproblem 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 '(5 + -2x)' equal to zero and attempt to solve: Simplifying 5 + -2x = 0 Solving 5 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -2x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -2x = 0 + -5 -2x = 0 + -5 Combine like terms: 0 + -5 = -5 -2x = -5 Divide each side by '-2'. x = 2.5 Simplifying x = 2.5Solution
x = {0, 2.5}
