Simplifying 2x3 + -30x = 0 Reorder the terms: -30x + 2x3 = 0 Solving -30x + 2x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x'. 2x(-15 + x2) = 0 Ignore the factor 2.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 '(-15 + x2)' equal to zero and attempt to solve: Simplifying -15 + x2 = 0 Solving -15 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + x2 = 0 + 15 Combine like terms: -15 + 15 = 0 0 + x2 = 0 + 15 x2 = 0 + 15 Combine like terms: 0 + 15 = 15 x2 = 15 Simplifying x2 = 15 Take the square root of each side: x = {-3.872983346, 3.872983346}Solution
x = {0, -3.872983346, 3.872983346}
