Simplifying 3x2 + -21x6 = 0 Solving 3x2 + -21x6 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3x2'. 3x2(1 + -7x4) = 0 Ignore the factor 3.Subproblem 1
Set the factor 'x2' equal to zero and attempt to solve: Simplifying x2 = 0 Solving x2 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x2 = 0 Take the square root of each side: x = {0}Subproblem 2
Set the factor '(1 + -7x4)' equal to zero and attempt to solve: Simplifying 1 + -7x4 = 0 Solving 1 + -7x4 = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -7x4 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -7x4 = 0 + -1 -7x4 = 0 + -1 Combine like terms: 0 + -1 = -1 -7x4 = -1 Divide each side by '-7'. x4 = 0.1428571429 Simplifying x4 = 0.1428571429 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
