Simplifying 21ab2 + 35a2b = 0 Solving 21ab2 + 35a2b = 0 Solving for variable 'a'. Factor out the Greatest Common Factor (GCF), '7ab'. 7ab(3b + 5a) = 0 Ignore the factor 7.Subproblem 1
Set the factor 'ab' equal to zero and attempt to solve: Simplifying ab = 0 Solving ab = 0 Move all terms containing a to the left, all other terms to the right. Simplifying ab = 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 '(3b + 5a)' equal to zero and attempt to solve: Simplifying 3b + 5a = 0 Reorder the terms: 5a + 3b = 0 Solving 5a + 3b = 0 Move all terms containing a to the left, all other terms to the right. Add '-3b' to each side of the equation. 5a + 3b + -3b = 0 + -3b Combine like terms: 3b + -3b = 0 5a + 0 = 0 + -3b 5a = 0 + -3b Remove the zero: 5a = -3b Divide each side by '5'. a = -0.6b Simplifying a = -0.6bSolution
a = {-0.6b}
