Simplifying b2 + 8b = -13 Reorder the terms: 8b + b2 = -13 Solving 8b + b2 = -13 Solving for variable 'b'. Reorder the terms: 13 + 8b + b2 = -13 + 13 Combine like terms: -13 + 13 = 0 13 + 8b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + 8b + -13 + b2 = 0 + -13 Reorder the terms: 13 + -13 + 8b + b2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 8b + b2 = 0 + -13 8b + b2 = 0 + -13 Combine like terms: 0 + -13 = -13 8b + b2 = -13 The b term is 8b. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8b + 16 + b2 = -13 + 16 Reorder the terms: 16 + 8b + b2 = -13 + 16 Combine like terms: -13 + 16 = 3 16 + 8b + b2 = 3 Factor a perfect square on the left side: (b + 4)(b + 4) = 3 Calculate the square root of the right side: 1.732050808 Break this problem into two subproblems by setting (b + 4) equal to 1.732050808 and -1.732050808.Subproblem 1
b + 4 = 1.732050808 Simplifying b + 4 = 1.732050808 Reorder the terms: 4 + b = 1.732050808 Solving 4 + b = 1.732050808 Solving for variable 'b'. 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 = 1.732050808 + -4 Combine like terms: 4 + -4 = 0 0 + b = 1.732050808 + -4 b = 1.732050808 + -4 Combine like terms: 1.732050808 + -4 = -2.267949192 b = -2.267949192 Simplifying b = -2.267949192Subproblem 2
b + 4 = -1.732050808 Simplifying b + 4 = -1.732050808 Reorder the terms: 4 + b = -1.732050808 Solving 4 + b = -1.732050808 Solving for variable 'b'. 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 = -1.732050808 + -4 Combine like terms: 4 + -4 = 0 0 + b = -1.732050808 + -4 b = -1.732050808 + -4 Combine like terms: -1.732050808 + -4 = -5.732050808 b = -5.732050808 Simplifying b = -5.732050808Solution
