Simplifying (b + 7)(b + -15) = 0 Reorder the terms: (7 + b)(b + -15) = 0 Reorder the terms: (7 + b)(-15 + b) = 0 Multiply (7 + b) * (-15 + b) (7(-15 + b) + b(-15 + b)) = 0 ((-15 * 7 + b * 7) + b(-15 + b)) = 0 ((-105 + 7b) + b(-15 + b)) = 0 (-105 + 7b + (-15 * b + b * b)) = 0 (-105 + 7b + (-15b + b2)) = 0 Combine like terms: 7b + -15b = -8b (-105 + -8b + b2) = 0 Solving -105 + -8b + b2 = 0 Solving for variable 'b'. Factor a trinomial. (-7 + -1b)(15 + -1b) = 0Subproblem 1
Set the factor '(-7 + -1b)' equal to zero and attempt to solve: Simplifying -7 + -1b = 0 Solving -7 + -1b = 0 Move all terms containing b to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -1b = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1b = 0 + 7 -1b = 0 + 7 Combine like terms: 0 + 7 = 7 -1b = 7 Divide each side by '-1'. b = -7 Simplifying b = -7Subproblem 2
Set the factor '(15 + -1b)' equal to zero and attempt to solve: Simplifying 15 + -1b = 0 Solving 15 + -1b = 0 Move all terms containing b to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + -1b = 0 + -15 Combine like terms: 15 + -15 = 0 0 + -1b = 0 + -15 -1b = 0 + -15 Combine like terms: 0 + -15 = -15 -1b = -15 Divide each side by '-1'. b = 15 Simplifying b = 15Solution
b = {-7, 15}
