Simplifying b(20b + -33) + -2 = 0 Reorder the terms: b(-33 + 20b) + -2 = 0 (-33 * b + 20b * b) + -2 = 0 (-33b + 20b2) + -2 = 0 Reorder the terms: -2 + -33b + 20b2 = 0 Solving -2 + -33b + 20b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -0.1 + -1.65b + b2 = 0 Move the constant term to the right: Add '0.1' to each side of the equation. -0.1 + -1.65b + 0.1 + b2 = 0 + 0.1 Reorder the terms: -0.1 + 0.1 + -1.65b + b2 = 0 + 0.1 Combine like terms: -0.1 + 0.1 = 0.0 0.0 + -1.65b + b2 = 0 + 0.1 -1.65b + b2 = 0 + 0.1 Combine like terms: 0 + 0.1 = 0.1 -1.65b + b2 = 0.1 The b term is -1.65b. Take half its coefficient (-0.825). Square it (0.680625) and add it to both sides. Add '0.680625' to each side of the equation. -1.65b + 0.680625 + b2 = 0.1 + 0.680625 Reorder the terms: 0.680625 + -1.65b + b2 = 0.1 + 0.680625 Combine like terms: 0.1 + 0.680625 = 0.780625 0.680625 + -1.65b + b2 = 0.780625 Factor a perfect square on the left side: (b + -0.825)(b + -0.825) = 0.780625 Calculate the square root of the right side: 0.883529852 Break this problem into two subproblems by setting (b + -0.825) equal to 0.883529852 and -0.883529852.Subproblem 1
b + -0.825 = 0.883529852 Simplifying b + -0.825 = 0.883529852 Reorder the terms: -0.825 + b = 0.883529852 Solving -0.825 + b = 0.883529852 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '0.825' to each side of the equation. -0.825 + 0.825 + b = 0.883529852 + 0.825 Combine like terms: -0.825 + 0.825 = 0.000 0.000 + b = 0.883529852 + 0.825 b = 0.883529852 + 0.825 Combine like terms: 0.883529852 + 0.825 = 1.708529852 b = 1.708529852 Simplifying b = 1.708529852Subproblem 2
b + -0.825 = -0.883529852 Simplifying b + -0.825 = -0.883529852 Reorder the terms: -0.825 + b = -0.883529852 Solving -0.825 + b = -0.883529852 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '0.825' to each side of the equation. -0.825 + 0.825 + b = -0.883529852 + 0.825 Combine like terms: -0.825 + 0.825 = 0.000 0.000 + b = -0.883529852 + 0.825 b = -0.883529852 + 0.825 Combine like terms: -0.883529852 + 0.825 = -0.058529852 b = -0.058529852 Simplifying b = -0.058529852Solution
The solution to the problem is based on the solutions from the subproblems. b = {1.708529852, -0.058529852}
