Simplifying 2b2 + -5b + 1 = 0 Reorder the terms: 1 + -5b + 2b2 = 0 Solving 1 + -5b + 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'. 0.5 + -2.5b + b2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -2.5b + -0.5 + b2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -2.5b + b2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -2.5b + b2 = 0 + -0.5 -2.5b + b2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -2.5b + b2 = -0.5 The b term is -2.5b. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5b + 1.5625 + b2 = -0.5 + 1.5625 Reorder the terms: 1.5625 + -2.5b + b2 = -0.5 + 1.5625 Combine like terms: -0.5 + 1.5625 = 1.0625 1.5625 + -2.5b + b2 = 1.0625 Factor a perfect square on the left side: (b + -1.25)(b + -1.25) = 1.0625 Calculate the square root of the right side: 1.030776406 Break this problem into two subproblems by setting (b + -1.25) equal to 1.030776406 and -1.030776406.Subproblem 1
b + -1.25 = 1.030776406 Simplifying b + -1.25 = 1.030776406 Reorder the terms: -1.25 + b = 1.030776406 Solving -1.25 + b = 1.030776406 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + b = 1.030776406 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + b = 1.030776406 + 1.25 b = 1.030776406 + 1.25 Combine like terms: 1.030776406 + 1.25 = 2.280776406 b = 2.280776406 Simplifying b = 2.280776406Subproblem 2
b + -1.25 = -1.030776406 Simplifying b + -1.25 = -1.030776406 Reorder the terms: -1.25 + b = -1.030776406 Solving -1.25 + b = -1.030776406 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + b = -1.030776406 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + b = -1.030776406 + 1.25 b = -1.030776406 + 1.25 Combine like terms: -1.030776406 + 1.25 = 0.219223594 b = 0.219223594 Simplifying b = 0.219223594Solution
