Simplifying (b)(b) + 20b + 36 = 0 Multiply b * b b2 + 20b + 36 = 0 Reorder the terms: 36 + 20b + b2 = 0 Solving 36 + 20b + b2 = 0 Solving for variable 'b'. Factor a trinomial. (18 + b)(2 + b) = 0Subproblem 1
Set the factor '(18 + b)' equal to zero and attempt to solve: Simplifying 18 + b = 0 Solving 18 + b = 0 Move all terms containing b to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + -18 + b = 0 + -18 Combine like terms: 18 + -18 = 0 0 + b = 0 + -18 b = 0 + -18 Combine like terms: 0 + -18 = -18 b = -18 Simplifying b = -18Subproblem 2
Set the factor '(2 + b)' equal to zero and attempt to solve: Simplifying 2 + b = 0 Solving 2 + b = 0 Move all terms containing b to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + b = 0 + -2 Combine like terms: 2 + -2 = 0 0 + b = 0 + -2 b = 0 + -2 Combine like terms: 0 + -2 = -2 b = -2 Simplifying b = -2Solution
b = {-18, -2}
