Simplifying b2 + -7b = 23 Reorder the terms: -7b + b2 = 23 Solving -7b + b2 = 23 Solving for variable 'b'. Reorder the terms: -23 + -7b + b2 = 23 + -23 Combine like terms: 23 + -23 = 0 -23 + -7b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '23' to each side of the equation. -23 + -7b + 23 + b2 = 0 + 23 Reorder the terms: -23 + 23 + -7b + b2 = 0 + 23 Combine like terms: -23 + 23 = 0 0 + -7b + b2 = 0 + 23 -7b + b2 = 0 + 23 Combine like terms: 0 + 23 = 23 -7b + b2 = 23 The b term is -7b. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7b + 12.25 + b2 = 23 + 12.25 Reorder the terms: 12.25 + -7b + b2 = 23 + 12.25 Combine like terms: 23 + 12.25 = 35.25 12.25 + -7b + b2 = 35.25 Factor a perfect square on the left side: (b + -3.5)(b + -3.5) = 35.25 Calculate the square root of the right side: 5.937171044 Break this problem into two subproblems by setting (b + -3.5) equal to 5.937171044 and -5.937171044.Subproblem 1
b + -3.5 = 5.937171044 Simplifying b + -3.5 = 5.937171044 Reorder the terms: -3.5 + b = 5.937171044 Solving -3.5 + b = 5.937171044 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + b = 5.937171044 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + b = 5.937171044 + 3.5 b = 5.937171044 + 3.5 Combine like terms: 5.937171044 + 3.5 = 9.437171044 b = 9.437171044 Simplifying b = 9.437171044Subproblem 2
b + -3.5 = -5.937171044 Simplifying b + -3.5 = -5.937171044 Reorder the terms: -3.5 + b = -5.937171044 Solving -3.5 + b = -5.937171044 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + b = -5.937171044 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + b = -5.937171044 + 3.5 b = -5.937171044 + 3.5 Combine like terms: -5.937171044 + 3.5 = -2.437171044 b = -2.437171044 Simplifying b = -2.437171044Solution
The solution to the problem is based on the solutions from the subproblems. b = {9.437171044, -2.437171044}
