Simplifying b2 + 18b + 43 = 0 Reorder the terms: 43 + 18b + b2 = 0 Solving 43 + 18b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-43' to each side of the equation. 43 + 18b + -43 + b2 = 0 + -43 Reorder the terms: 43 + -43 + 18b + b2 = 0 + -43 Combine like terms: 43 + -43 = 0 0 + 18b + b2 = 0 + -43 18b + b2 = 0 + -43 Combine like terms: 0 + -43 = -43 18b + b2 = -43 The b term is 18b. Take half its coefficient (9). Square it (81) and add it to both sides. Add '81' to each side of the equation. 18b + 81 + b2 = -43 + 81 Reorder the terms: 81 + 18b + b2 = -43 + 81 Combine like terms: -43 + 81 = 38 81 + 18b + b2 = 38 Factor a perfect square on the left side: (b + 9)(b + 9) = 38 Calculate the square root of the right side: 6.164414003 Break this problem into two subproblems by setting (b + 9) equal to 6.164414003 and -6.164414003.Subproblem 1
b + 9 = 6.164414003 Simplifying b + 9 = 6.164414003 Reorder the terms: 9 + b = 6.164414003 Solving 9 + b = 6.164414003 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + b = 6.164414003 + -9 Combine like terms: 9 + -9 = 0 0 + b = 6.164414003 + -9 b = 6.164414003 + -9 Combine like terms: 6.164414003 + -9 = -2.835585997 b = -2.835585997 Simplifying b = -2.835585997Subproblem 2
b + 9 = -6.164414003 Simplifying b + 9 = -6.164414003 Reorder the terms: 9 + b = -6.164414003 Solving 9 + b = -6.164414003 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + b = -6.164414003 + -9 Combine like terms: 9 + -9 = 0 0 + b = -6.164414003 + -9 b = -6.164414003 + -9 Combine like terms: -6.164414003 + -9 = -15.164414003 b = -15.164414003 Simplifying b = -15.164414003Solution
The solution to the problem is based on the solutions from the subproblems. b = {-2.835585997, -15.164414003}
