Simplifying 4b2 + 20b = 25 Reorder the terms: 20b + 4b2 = 25 Solving 20b + 4b2 = 25 Solving for variable 'b'. Reorder the terms: -25 + 20b + 4b2 = 25 + -25 Combine like terms: 25 + -25 = 0 -25 + 20b + 4b2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -6.25 + 5b + b2 = 0 Move the constant term to the right: Add '6.25' to each side of the equation. -6.25 + 5b + 6.25 + b2 = 0 + 6.25 Reorder the terms: -6.25 + 6.25 + 5b + b2 = 0 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + 5b + b2 = 0 + 6.25 5b + b2 = 0 + 6.25 Combine like terms: 0 + 6.25 = 6.25 5b + b2 = 6.25 The b term is 5b. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5b + 6.25 + b2 = 6.25 + 6.25 Reorder the terms: 6.25 + 5b + b2 = 6.25 + 6.25 Combine like terms: 6.25 + 6.25 = 12.5 6.25 + 5b + b2 = 12.5 Factor a perfect square on the left side: (b + 2.5)(b + 2.5) = 12.5 Calculate the square root of the right side: 3.535533906 Break this problem into two subproblems by setting (b + 2.5) equal to 3.535533906 and -3.535533906.Subproblem 1
b + 2.5 = 3.535533906 Simplifying b + 2.5 = 3.535533906 Reorder the terms: 2.5 + b = 3.535533906 Solving 2.5 + b = 3.535533906 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + b = 3.535533906 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + b = 3.535533906 + -2.5 b = 3.535533906 + -2.5 Combine like terms: 3.535533906 + -2.5 = 1.035533906 b = 1.035533906 Simplifying b = 1.035533906Subproblem 2
b + 2.5 = -3.535533906 Simplifying b + 2.5 = -3.535533906 Reorder the terms: 2.5 + b = -3.535533906 Solving 2.5 + b = -3.535533906 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + b = -3.535533906 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + b = -3.535533906 + -2.5 b = -3.535533906 + -2.5 Combine like terms: -3.535533906 + -2.5 = -6.035533906 b = -6.035533906 Simplifying b = -6.035533906Solution
The solution to the problem is based on the solutions from the subproblems. b = {1.035533906, -6.035533906}
