Simplifying 20b2 + -20b + 1 = 0 Reorder the terms: 1 + -20b + 20b2 = 0 Solving 1 + -20b + 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'. 0.05 + -1b + b2 = 0 Move the constant term to the right: Add '-0.05' to each side of the equation. 0.05 + -1b + -0.05 + b2 = 0 + -0.05 Reorder the terms: 0.05 + -0.05 + -1b + b2 = 0 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + -1b + b2 = 0 + -0.05 -1b + b2 = 0 + -0.05 Combine like terms: 0 + -0.05 = -0.05 -1b + b2 = -0.05 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 = -0.05 + 0.25 Reorder the terms: 0.25 + -1b + b2 = -0.05 + 0.25 Combine like terms: -0.05 + 0.25 = 0.2 0.25 + -1b + b2 = 0.2 Factor a perfect square on the left side: (b + -0.5)(b + -0.5) = 0.2 Calculate the square root of the right side: 0.447213596 Break this problem into two subproblems by setting (b + -0.5) equal to 0.447213596 and -0.447213596.Subproblem 1
b + -0.5 = 0.447213596 Simplifying b + -0.5 = 0.447213596 Reorder the terms: -0.5 + b = 0.447213596 Solving -0.5 + b = 0.447213596 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 = 0.447213596 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + b = 0.447213596 + 0.5 b = 0.447213596 + 0.5 Combine like terms: 0.447213596 + 0.5 = 0.947213596 b = 0.947213596 Simplifying b = 0.947213596Subproblem 2
b + -0.5 = -0.447213596 Simplifying b + -0.5 = -0.447213596 Reorder the terms: -0.5 + b = -0.447213596 Solving -0.5 + b = -0.447213596 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 = -0.447213596 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + b = -0.447213596 + 0.5 b = -0.447213596 + 0.5 Combine like terms: -0.447213596 + 0.5 = 0.052786404 b = 0.052786404 Simplifying b = 0.052786404Solution
