Simplifying b2 + 5b = 28 Reorder the terms: 5b + b2 = 28 Solving 5b + b2 = 28 Solving for variable 'b'. Reorder the terms: -28 + 5b + b2 = 28 + -28 Combine like terms: 28 + -28 = 0 -28 + 5b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '28' to each side of the equation. -28 + 5b + 28 + b2 = 0 + 28 Reorder the terms: -28 + 28 + 5b + b2 = 0 + 28 Combine like terms: -28 + 28 = 0 0 + 5b + b2 = 0 + 28 5b + b2 = 0 + 28 Combine like terms: 0 + 28 = 28 5b + b2 = 28 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 = 28 + 6.25 Reorder the terms: 6.25 + 5b + b2 = 28 + 6.25 Combine like terms: 28 + 6.25 = 34.25 6.25 + 5b + b2 = 34.25 Factor a perfect square on the left side: (b + 2.5)(b + 2.5) = 34.25 Calculate the square root of the right side: 5.852349955 Break this problem into two subproblems by setting (b + 2.5) equal to 5.852349955 and -5.852349955.Subproblem 1
b + 2.5 = 5.852349955 Simplifying b + 2.5 = 5.852349955 Reorder the terms: 2.5 + b = 5.852349955 Solving 2.5 + b = 5.852349955 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 = 5.852349955 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + b = 5.852349955 + -2.5 b = 5.852349955 + -2.5 Combine like terms: 5.852349955 + -2.5 = 3.352349955 b = 3.352349955 Simplifying b = 3.352349955Subproblem 2
b + 2.5 = -5.852349955 Simplifying b + 2.5 = -5.852349955 Reorder the terms: 2.5 + b = -5.852349955 Solving 2.5 + b = -5.852349955 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 = -5.852349955 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + b = -5.852349955 + -2.5 b = -5.852349955 + -2.5 Combine like terms: -5.852349955 + -2.5 = -8.352349955 b = -8.352349955 Simplifying b = -8.352349955Solution
The solution to the problem is based on the solutions from the subproblems. b = {3.352349955, -8.352349955}
