Simplifying 84x3 + -12xy + 20x = 0 Reorder the terms: 20x + -12xy + 84x3 = 0 Solving 20x + -12xy + 84x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4x'. 4x(5 + -3y + 21x2) = 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 '(5 + -3y + 21x2)' equal to zero and attempt to solve: Simplifying 5 + -3y + 21x2 = 0 Reorder the terms: 5 + 21x2 + -3y = 0 Solving 5 + 21x2 + -3y = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + 21x2 + -5 + -3y = 0 + -5 Reorder the terms: 5 + -5 + 21x2 + -3y = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 21x2 + -3y = 0 + -5 21x2 + -3y = 0 + -5 Combine like terms: 0 + -5 = -5 21x2 + -3y = -5 Add '3y' to each side of the equation. 21x2 + -3y + 3y = -5 + 3y Combine like terms: -3y + 3y = 0 21x2 + 0 = -5 + 3y 21x2 = -5 + 3y Divide each side by '21'. x2 = -0.2380952381 + 0.1428571429y Simplifying x2 = -0.2380952381 + 0.1428571429y The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
