Simplifying 2b2 + -2b + -5 = 0 Reorder the terms: -5 + -2b + 2b2 = 0 Solving -5 + -2b + 2b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2.5 + -1b + b2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + -1b + 2.5 + b2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + -1b + b2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + -1b + b2 = 0 + 2.5 -1b + b2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 -1b + b2 = 2.5 The b term is -1b. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1b + 0.25 + b2 = 2.5 + 0.25 Reorder the terms: 0.25 + -1b + b2 = 2.5 + 0.25 Combine like terms: 2.5 + 0.25 = 2.75 0.25 + -1b + b2 = 2.75 Factor a perfect square on the left side: (b + -0.5)(b + -0.5) = 2.75 Calculate the square root of the right side: 1.658312395 Break this problem into two subproblems by setting (b + -0.5) equal to 1.658312395 and -1.658312395.Subproblem 1
b + -0.5 = 1.658312395 Simplifying b + -0.5 = 1.658312395 Reorder the terms: -0.5 + b = 1.658312395 Solving -0.5 + b = 1.658312395 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + b = 1.658312395 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + b = 1.658312395 + 0.5 b = 1.658312395 + 0.5 Combine like terms: 1.658312395 + 0.5 = 2.158312395 b = 2.158312395 Simplifying b = 2.158312395Subproblem 2
b + -0.5 = -1.658312395 Simplifying b + -0.5 = -1.658312395 Reorder the terms: -0.5 + b = -1.658312395 Solving -0.5 + b = -1.658312395 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + b = -1.658312395 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + b = -1.658312395 + 0.5 b = -1.658312395 + 0.5 Combine like terms: -1.658312395 + 0.5 = -1.158312395 b = -1.158312395 Simplifying b = -1.158312395Solution
The solution to the problem is based on the solutions from the subproblems. b = {2.158312395, -1.158312395}
