Simplifying 4x3 + -40x = 0 Reorder the terms: -40x + 4x3 = 0 Solving -40x + 4x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4x'. 4x(-10 + x2) = 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 '(-10 + x2)' equal to zero and attempt to solve: Simplifying -10 + x2 = 0 Solving -10 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + x2 = 0 + 10 x2 = 0 + 10 Combine like terms: 0 + 10 = 10 x2 = 10 Simplifying x2 = 10 Take the square root of each side: x = {-3.16227766, 3.16227766}Solution
x = {0, -3.16227766, 3.16227766}
