Simplifying 12ab2 + 42a2b = 0 Solving 12ab2 + 42a2b = 0 Solving for variable 'a'. Factor out the Greatest Common Factor (GCF), '6ab'. 6ab(2b + 7a) = 0 Ignore the factor 6.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 '(2b + 7a)' equal to zero and attempt to solve: Simplifying 2b + 7a = 0 Reorder the terms: 7a + 2b = 0 Solving 7a + 2b = 0 Move all terms containing a to the left, all other terms to the right. Add '-2b' to each side of the equation. 7a + 2b + -2b = 0 + -2b Combine like terms: 2b + -2b = 0 7a + 0 = 0 + -2b 7a = 0 + -2b Remove the zero: 7a = -2b Divide each side by '7'. a = -0.2857142857b Simplifying a = -0.2857142857bSolution
a = {-0.2857142857b}
