Simplifying b2 + -2b + -75 = 0 Reorder the terms: -75 + -2b + b2 = 0 Solving -75 + -2b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '75' to each side of the equation. -75 + -2b + 75 + b2 = 0 + 75 Reorder the terms: -75 + 75 + -2b + b2 = 0 + 75 Combine like terms: -75 + 75 = 0 0 + -2b + b2 = 0 + 75 -2b + b2 = 0 + 75 Combine like terms: 0 + 75 = 75 -2b + b2 = 75 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 = 75 + 1 Reorder the terms: 1 + -2b + b2 = 75 + 1 Combine like terms: 75 + 1 = 76 1 + -2b + b2 = 76 Factor a perfect square on the left side: (b + -1)(b + -1) = 76 Calculate the square root of the right side: 8.717797887 Break this problem into two subproblems by setting (b + -1) equal to 8.717797887 and -8.717797887.Subproblem 1
b + -1 = 8.717797887 Simplifying b + -1 = 8.717797887 Reorder the terms: -1 + b = 8.717797887 Solving -1 + b = 8.717797887 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 = 8.717797887 + 1 Combine like terms: -1 + 1 = 0 0 + b = 8.717797887 + 1 b = 8.717797887 + 1 Combine like terms: 8.717797887 + 1 = 9.717797887 b = 9.717797887 Simplifying b = 9.717797887Subproblem 2
b + -1 = -8.717797887 Simplifying b + -1 = -8.717797887 Reorder the terms: -1 + b = -8.717797887 Solving -1 + b = -8.717797887 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 = -8.717797887 + 1 Combine like terms: -1 + 1 = 0 0 + b = -8.717797887 + 1 b = -8.717797887 + 1 Combine like terms: -8.717797887 + 1 = -7.717797887 b = -7.717797887 Simplifying b = -7.717797887Solution
The solution to the problem is based on the solutions from the subproblems. b = {9.717797887, -7.717797887}
