Simplifying 4b(7b + -4) = 0 Reorder the terms: 4b(-4 + 7b) = 0 (-4 * 4b + 7b * 4b) = 0 (-16b + 28b2) = 0 Solving -16b + 28b2 = 0 Solving for variable 'b'. Factor out the Greatest Common Factor (GCF), '4b'. 4b(-4 + 7b) = 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 + 7b)' equal to zero and attempt to solve: Simplifying -4 + 7b = 0 Solving -4 + 7b = 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 + 7b = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 7b = 0 + 4 7b = 0 + 4 Combine like terms: 0 + 4 = 4 7b = 4 Divide each side by '7'. b = 0.5714285714 Simplifying b = 0.5714285714Solution
b = {0, 0.5714285714}
