Simplifying 12.5b2 + 5b + 0.5 = 0 Reorder the terms: 0.5 + 5b + 12.5b2 = 0 Solving 0.5 + 5b + 12.5b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 12.5 the coefficient of the squared term: Divide each side by '12.5'. 0.04 + 0.4b + b2 = 0 Move the constant term to the right: Add '-0.04' to each side of the equation. 0.04 + 0.4b + -0.04 + b2 = 0 + -0.04 Reorder the terms: 0.04 + -0.04 + 0.4b + b2 = 0 + -0.04 Combine like terms: 0.04 + -0.04 = 0.00 0.00 + 0.4b + b2 = 0 + -0.04 0.4b + b2 = 0 + -0.04 Combine like terms: 0 + -0.04 = -0.04 0.4b + b2 = -0.04 The b term is 0.4b. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4b + 0.04 + b2 = -0.04 + 0.04 Reorder the terms: 0.04 + 0.4b + b2 = -0.04 + 0.04 Combine like terms: -0.04 + 0.04 = 0.00 0.04 + 0.4b + b2 = 0.00 Factor a perfect square on the left side: (b + 0.2)(b + 0.2) = 0.00 Calculate the square root of the right side: 0.00 Break this problem into two subproblems by setting (b + 0.2) equal to 0.00 and 0.00.Subproblem 1
b + 0.2 = 0.00 Simplifying b + 0.2 = 0.00 Reorder the terms: 0.2 + b = 0.00 Solving 0.2 + b = 0.00 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + b = 0.00 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + b = 0.00 + -0.2 b = 0.00 + -0.2 Combine like terms: 0.00 + -0.2 = -0.2 b = -0.2 Simplifying b = -0.2Subproblem 2
b + 0.2 = 0.00 Simplifying b + 0.2 = 0.00 Reorder the terms: 0.2 + b = 0.00 Solving 0.2 + b = 0.00 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + b = 0.00 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + b = 0.00 + -0.2 b = 0.00 + -0.2 Combine like terms: 0.00 + -0.2 = -0.2 b = -0.2 Simplifying b = -0.2Solution
The solution to the problem is based on the solutions from the subproblems. b = {-0.2, -0.2}
