Simplifying b2 + 8b + -22 = 0 Reorder the terms: -22 + 8b + b2 = 0 Solving -22 + 8b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '22' to each side of the equation. -22 + 8b + 22 + b2 = 0 + 22 Reorder the terms: -22 + 22 + 8b + b2 = 0 + 22 Combine like terms: -22 + 22 = 0 0 + 8b + b2 = 0 + 22 8b + b2 = 0 + 22 Combine like terms: 0 + 22 = 22 8b + b2 = 22 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 = 22 + 16 Reorder the terms: 16 + 8b + b2 = 22 + 16 Combine like terms: 22 + 16 = 38 16 + 8b + b2 = 38 Factor a perfect square on the left side: (b + 4)(b + 4) = 38 Calculate the square root of the right side: 6.164414003 Break this problem into two subproblems by setting (b + 4) equal to 6.164414003 and -6.164414003.Subproblem 1
b + 4 = 6.164414003 Simplifying b + 4 = 6.164414003 Reorder the terms: 4 + b = 6.164414003 Solving 4 + b = 6.164414003 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 = 6.164414003 + -4 Combine like terms: 4 + -4 = 0 0 + b = 6.164414003 + -4 b = 6.164414003 + -4 Combine like terms: 6.164414003 + -4 = 2.164414003 b = 2.164414003 Simplifying b = 2.164414003Subproblem 2
b + 4 = -6.164414003 Simplifying b + 4 = -6.164414003 Reorder the terms: 4 + b = -6.164414003 Solving 4 + b = -6.164414003 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 = -6.164414003 + -4 Combine like terms: 4 + -4 = 0 0 + b = -6.164414003 + -4 b = -6.164414003 + -4 Combine like terms: -6.164414003 + -4 = -10.164414003 b = -10.164414003 Simplifying b = -10.164414003Solution
The solution to the problem is based on the solutions from the subproblems. b = {2.164414003, -10.164414003}
