Simplifying b2 = -1 + -8b Solving b2 = -1 + -8b Solving for variable 'b'. Reorder the terms: 1 + 8b + b2 = -1 + -8b + 1 + 8b Reorder the terms: 1 + 8b + b2 = -1 + 1 + -8b + 8b Combine like terms: -1 + 1 = 0 1 + 8b + b2 = 0 + -8b + 8b 1 + 8b + b2 = -8b + 8b Combine like terms: -8b + 8b = 0 1 + 8b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + 8b + -1 + b2 = 0 + -1 Reorder the terms: 1 + -1 + 8b + b2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 8b + b2 = 0 + -1 8b + b2 = 0 + -1 Combine like terms: 0 + -1 = -1 8b + b2 = -1 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 = -1 + 16 Reorder the terms: 16 + 8b + b2 = -1 + 16 Combine like terms: -1 + 16 = 15 16 + 8b + b2 = 15 Factor a perfect square on the left side: (b + 4)(b + 4) = 15 Calculate the square root of the right side: 3.872983346 Break this problem into two subproblems by setting (b + 4) equal to 3.872983346 and -3.872983346.Subproblem 1
b + 4 = 3.872983346 Simplifying b + 4 = 3.872983346 Reorder the terms: 4 + b = 3.872983346 Solving 4 + b = 3.872983346 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 = 3.872983346 + -4 Combine like terms: 4 + -4 = 0 0 + b = 3.872983346 + -4 b = 3.872983346 + -4 Combine like terms: 3.872983346 + -4 = -0.127016654 b = -0.127016654 Simplifying b = -0.127016654Subproblem 2
b + 4 = -3.872983346 Simplifying b + 4 = -3.872983346 Reorder the terms: 4 + b = -3.872983346 Solving 4 + b = -3.872983346 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 = -3.872983346 + -4 Combine like terms: 4 + -4 = 0 0 + b = -3.872983346 + -4 b = -3.872983346 + -4 Combine like terms: -3.872983346 + -4 = -7.872983346 b = -7.872983346 Simplifying b = -7.872983346Solution
