Simplifying 16b + 20b3 = 0 Solving 16b + 20b3 = 0 Solving for variable 'b'. Factor out the Greatest Common Factor (GCF), '4b'. 4b(4 + 5b2) = 0 Ignore the factor 4.Subproblem 1
Set the factor 'b' equal to zero and attempt to solve: Simplifying b = 0 Solving b = 0 Move all terms containing b to the left, all other terms to the right. Simplifying b = 0Subproblem 2
Set the factor '(4 + 5b2)' equal to zero and attempt to solve: Simplifying 4 + 5b2 = 0 Solving 4 + 5b2 = 0 Move all terms containing b to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + 5b2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 5b2 = 0 + -4 5b2 = 0 + -4 Combine like terms: 0 + -4 = -4 5b2 = -4 Divide each side by '5'. b2 = -0.8 Simplifying b2 = -0.8 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
