Simplifying b2 + 3b + -9 = 0 Reorder the terms: -9 + 3b + b2 = 0 Solving -9 + 3b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '9' to each side of the equation. -9 + 3b + 9 + b2 = 0 + 9 Reorder the terms: -9 + 9 + 3b + b2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 3b + b2 = 0 + 9 3b + b2 = 0 + 9 Combine like terms: 0 + 9 = 9 3b + b2 = 9 The b term is 3b. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3b + 2.25 + b2 = 9 + 2.25 Reorder the terms: 2.25 + 3b + b2 = 9 + 2.25 Combine like terms: 9 + 2.25 = 11.25 2.25 + 3b + b2 = 11.25 Factor a perfect square on the left side: (b + 1.5)(b + 1.5) = 11.25 Calculate the square root of the right side: 3.354101966 Break this problem into two subproblems by setting (b + 1.5) equal to 3.354101966 and -3.354101966.Subproblem 1
b + 1.5 = 3.354101966 Simplifying b + 1.5 = 3.354101966 Reorder the terms: 1.5 + b = 3.354101966 Solving 1.5 + b = 3.354101966 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + b = 3.354101966 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + b = 3.354101966 + -1.5 b = 3.354101966 + -1.5 Combine like terms: 3.354101966 + -1.5 = 1.854101966 b = 1.854101966 Simplifying b = 1.854101966Subproblem 2
b + 1.5 = -3.354101966 Simplifying b + 1.5 = -3.354101966 Reorder the terms: 1.5 + b = -3.354101966 Solving 1.5 + b = -3.354101966 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + b = -3.354101966 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + b = -3.354101966 + -1.5 b = -3.354101966 + -1.5 Combine like terms: -3.354101966 + -1.5 = -4.854101966 b = -4.854101966 Simplifying b = -4.854101966Solution
The solution to the problem is based on the solutions from the subproblems. b = {1.854101966, -4.854101966}
