Simplifying b2 + -2b + -72 = 0 Reorder the terms: -72 + -2b + b2 = 0 Solving -72 + -2b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '72' to each side of the equation. -72 + -2b + 72 + b2 = 0 + 72 Reorder the terms: -72 + 72 + -2b + b2 = 0 + 72 Combine like terms: -72 + 72 = 0 0 + -2b + b2 = 0 + 72 -2b + b2 = 0 + 72 Combine like terms: 0 + 72 = 72 -2b + b2 = 72 The b term is -2b. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2b + 1 + b2 = 72 + 1 Reorder the terms: 1 + -2b + b2 = 72 + 1 Combine like terms: 72 + 1 = 73 1 + -2b + b2 = 73 Factor a perfect square on the left side: (b + -1)(b + -1) = 73 Calculate the square root of the right side: 8.544003745 Break this problem into two subproblems by setting (b + -1) equal to 8.544003745 and -8.544003745.Subproblem 1
b + -1 = 8.544003745 Simplifying b + -1 = 8.544003745 Reorder the terms: -1 + b = 8.544003745 Solving -1 + b = 8.544003745 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + b = 8.544003745 + 1 Combine like terms: -1 + 1 = 0 0 + b = 8.544003745 + 1 b = 8.544003745 + 1 Combine like terms: 8.544003745 + 1 = 9.544003745 b = 9.544003745 Simplifying b = 9.544003745Subproblem 2
b + -1 = -8.544003745 Simplifying b + -1 = -8.544003745 Reorder the terms: -1 + b = -8.544003745 Solving -1 + b = -8.544003745 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + b = -8.544003745 + 1 Combine like terms: -1 + 1 = 0 0 + b = -8.544003745 + 1 b = -8.544003745 + 1 Combine like terms: -8.544003745 + 1 = -7.544003745 b = -7.544003745 Simplifying b = -7.544003745Solution
The solution to the problem is based on the solutions from the subproblems. b = {9.544003745, -7.544003745}
