Simplifying 20x3 = 50x Solving 20x3 = 50x Solving for variable 'x'. Reorder the terms: -50x + 20x3 = 50x + -50x Combine like terms: 50x + -50x = 0 -50x + 20x3 = 0 Factor out the Greatest Common Factor (GCF), '10x'. 10x(-5 + 2x2) = 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 '(-5 + 2x2)' equal to zero and attempt to solve: Simplifying -5 + 2x2 = 0 Solving -5 + 2x2 = 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 + 2x2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 2x2 = 0 + 5 2x2 = 0 + 5 Combine like terms: 0 + 5 = 5 2x2 = 5 Divide each side by '2'. x2 = 2.5 Simplifying x2 = 2.5 Take the square root of each side: x = {-1.58113883, 1.58113883}Solution
x = {0, -1.58113883, 1.58113883}
