Simplifying b2 + -11b = -15 Reorder the terms: -11b + b2 = -15 Solving -11b + b2 = -15 Solving for variable 'b'. Reorder the terms: 15 + -11b + b2 = -15 + 15 Combine like terms: -15 + 15 = 0 15 + -11b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '-15' to each side of the equation. 15 + -11b + -15 + b2 = 0 + -15 Reorder the terms: 15 + -15 + -11b + b2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + -11b + b2 = 0 + -15 -11b + b2 = 0 + -15 Combine like terms: 0 + -15 = -15 -11b + b2 = -15 The b term is -11b. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11b + 30.25 + b2 = -15 + 30.25 Reorder the terms: 30.25 + -11b + b2 = -15 + 30.25 Combine like terms: -15 + 30.25 = 15.25 30.25 + -11b + b2 = 15.25 Factor a perfect square on the left side: (b + -5.5)(b + -5.5) = 15.25 Calculate the square root of the right side: 3.905124838 Break this problem into two subproblems by setting (b + -5.5) equal to 3.905124838 and -3.905124838.Subproblem 1
b + -5.5 = 3.905124838 Simplifying b + -5.5 = 3.905124838 Reorder the terms: -5.5 + b = 3.905124838 Solving -5.5 + b = 3.905124838 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + b = 3.905124838 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + b = 3.905124838 + 5.5 b = 3.905124838 + 5.5 Combine like terms: 3.905124838 + 5.5 = 9.405124838 b = 9.405124838 Simplifying b = 9.405124838Subproblem 2
b + -5.5 = -3.905124838 Simplifying b + -5.5 = -3.905124838 Reorder the terms: -5.5 + b = -3.905124838 Solving -5.5 + b = -3.905124838 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + b = -3.905124838 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + b = -3.905124838 + 5.5 b = -3.905124838 + 5.5 Combine like terms: -3.905124838 + 5.5 = 1.594875162 b = 1.594875162 Simplifying b = 1.594875162Solution
