Simplifying ab + 3a = a Reorder the terms: 3a + ab = a Solving 3a + ab = a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-1a' to each side of the equation. 3a + -1a + ab = a + -1a Combine like terms: 3a + -1a = 2a 2a + ab = a + -1a Combine like terms: a + -1a = 0 2a + ab = 0 Factor out the Greatest Common Factor (GCF), 'a'. a(2 + b) = 0Subproblem 1
Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0Subproblem 2
Set the factor '(2 + b)' equal to zero and attempt to solve: Simplifying 2 + b = 0 Solving 2 + b = 0 Move all terms containing a to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + b = 0 + -2 Combine like terms: 2 + -2 = 0 0 + b = 0 + -2 b = 0 + -2 Combine like terms: 0 + -2 = -2 b = -2 Add '-1b' to each side of the equation. b + -1b = -2 + -1b Combine like terms: b + -1b = 0 0 = -2 + -1b Simplifying 0 = -2 + -1b The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
