Simplifying 5b2 + 32b + 20 = 0 Reorder the terms: 20 + 32b + 5b2 = 0 Solving 20 + 32b + 5b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 4 + 6.4b + b2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + 6.4b + -4 + b2 = 0 + -4 Reorder the terms: 4 + -4 + 6.4b + b2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 6.4b + b2 = 0 + -4 6.4b + b2 = 0 + -4 Combine like terms: 0 + -4 = -4 6.4b + b2 = -4 The b term is 6.4b. Take half its coefficient (3.2). Square it (10.24) and add it to both sides. Add '10.24' to each side of the equation. 6.4b + 10.24 + b2 = -4 + 10.24 Reorder the terms: 10.24 + 6.4b + b2 = -4 + 10.24 Combine like terms: -4 + 10.24 = 6.24 10.24 + 6.4b + b2 = 6.24 Factor a perfect square on the left side: (b + 3.2)(b + 3.2) = 6.24 Calculate the square root of the right side: 2.497999199 Break this problem into two subproblems by setting (b + 3.2) equal to 2.497999199 and -2.497999199.Subproblem 1
b + 3.2 = 2.497999199 Simplifying b + 3.2 = 2.497999199 Reorder the terms: 3.2 + b = 2.497999199 Solving 3.2 + b = 2.497999199 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-3.2' to each side of the equation. 3.2 + -3.2 + b = 2.497999199 + -3.2 Combine like terms: 3.2 + -3.2 = 0.0 0.0 + b = 2.497999199 + -3.2 b = 2.497999199 + -3.2 Combine like terms: 2.497999199 + -3.2 = -0.702000801 b = -0.702000801 Simplifying b = -0.702000801Subproblem 2
b + 3.2 = -2.497999199 Simplifying b + 3.2 = -2.497999199 Reorder the terms: 3.2 + b = -2.497999199 Solving 3.2 + b = -2.497999199 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-3.2' to each side of the equation. 3.2 + -3.2 + b = -2.497999199 + -3.2 Combine like terms: 3.2 + -3.2 = 0.0 0.0 + b = -2.497999199 + -3.2 b = -2.497999199 + -3.2 Combine like terms: -2.497999199 + -3.2 = -5.697999199 b = -5.697999199 Simplifying b = -5.697999199Solution
The solution to the problem is based on the solutions from the subproblems. b = {-0.702000801, -5.697999199}
