Simplifying b * b + 4b + 4 = 4 Multiply b * b b2 + 4b + 4 = 4 Reorder the terms: 4 + 4b + b2 = 4 Add '-4' to each side of the equation. 4 + 4b + -4 + b2 = 4 + -4 Reorder the terms: 4 + -4 + 4b + b2 = 4 + -4 Combine like terms: 4 + -4 = 0 0 + 4b + b2 = 4 + -4 4b + b2 = 4 + -4 Combine like terms: 4 + -4 = 0 4b + b2 = 0 Solving 4b + b2 = 0 Solving for variable 'b'. Factor out the Greatest Common Factor (GCF), 'b'. b(4 + b) = 0Subproblem 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 + b)' equal to zero and attempt to solve: Simplifying 4 + b = 0 Solving 4 + b = 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 + b = 0 + -4 Combine like terms: 4 + -4 = 0 0 + b = 0 + -4 b = 0 + -4 Combine like terms: 0 + -4 = -4 b = -4 Simplifying b = -4Solution
b = {0, -4}
