Simplifying 25b2 + -20b + 0 = 0 Reorder the terms: 0 + -20b + 25b2 = 0 Remove the zero: -20b + 25b2 = 0 Solving -20b + 25b2 = 0 Solving for variable 'b'. Factor out the Greatest Common Factor (GCF), '5b'. 5b(-4 + 5b) = 0 Ignore the factor 5.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 + 5b)' equal to zero and attempt to solve: Simplifying -4 + 5b = 0 Solving -4 + 5b = 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 + 5b = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 5b = 0 + 4 5b = 0 + 4 Combine like terms: 0 + 4 = 4 5b = 4 Divide each side by '5'. b = 0.8 Simplifying b = 0.8Solution
b = {0, 0.8}
