Simplifying b2 = 5b + 3 Reorder the terms: b2 = 3 + 5b Solving b2 = 3 + 5b Solving for variable 'b'. Reorder the terms: -3 + -5b + b2 = 3 + 5b + -3 + -5b Reorder the terms: -3 + -5b + b2 = 3 + -3 + 5b + -5b Combine like terms: 3 + -3 = 0 -3 + -5b + b2 = 0 + 5b + -5b -3 + -5b + b2 = 5b + -5b Combine like terms: 5b + -5b = 0 -3 + -5b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + -5b + 3 + b2 = 0 + 3 Reorder the terms: -3 + 3 + -5b + b2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -5b + b2 = 0 + 3 -5b + b2 = 0 + 3 Combine like terms: 0 + 3 = 3 -5b + b2 = 3 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 = 3 + 6.25 Reorder the terms: 6.25 + -5b + b2 = 3 + 6.25 Combine like terms: 3 + 6.25 = 9.25 6.25 + -5b + b2 = 9.25 Factor a perfect square on the left side: (b + -2.5)(b + -2.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (b + -2.5) equal to 3.041381265 and -3.041381265.Subproblem 1
b + -2.5 = 3.041381265 Simplifying b + -2.5 = 3.041381265 Reorder the terms: -2.5 + b = 3.041381265 Solving -2.5 + b = 3.041381265 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 = 3.041381265 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + b = 3.041381265 + 2.5 b = 3.041381265 + 2.5 Combine like terms: 3.041381265 + 2.5 = 5.541381265 b = 5.541381265 Simplifying b = 5.541381265Subproblem 2
b + -2.5 = -3.041381265 Simplifying b + -2.5 = -3.041381265 Reorder the terms: -2.5 + b = -3.041381265 Solving -2.5 + b = -3.041381265 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 = -3.041381265 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + b = -3.041381265 + 2.5 b = -3.041381265 + 2.5 Combine like terms: -3.041381265 + 2.5 = -0.541381265 b = -0.541381265 Simplifying b = -0.541381265Solution
The solution to the problem is based on the solutions from the subproblems. b = {5.541381265, -0.541381265}
