Simplifying 21x3y2 + 7xy = 0 Reorder the terms: 7xy + 21x3y2 = 0 Solving 7xy + 21x3y2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '7xy'. 7xy(1 + 3x2y) = 0 Ignore the factor 7.Subproblem 1
Set the factor 'xy' equal to zero and attempt to solve: Simplifying xy = 0 Solving xy = 0 Move all terms containing x to the left, all other terms to the right. Simplifying xy = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(1 + 3x2y)' equal to zero and attempt to solve: Simplifying 1 + 3x2y = 0 Solving 1 + 3x2y = 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 + 3x2y = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 3x2y = 0 + -1 3x2y = 0 + -1 Combine like terms: 0 + -1 = -1 3x2y = -1 Divide each side by '3y'. x2 = -0.3333333333y-1 Simplifying x2 = -0.3333333333y-1 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
