Simplifying b2 + -7b + 4 = 0 Reorder the terms: 4 + -7b + b2 = 0 Solving 4 + -7b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -7b + -4 + b2 = 0 + -4 Reorder the terms: 4 + -4 + -7b + b2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -7b + b2 = 0 + -4 -7b + b2 = 0 + -4 Combine like terms: 0 + -4 = -4 -7b + b2 = -4 The b term is -7b. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7b + 12.25 + b2 = -4 + 12.25 Reorder the terms: 12.25 + -7b + b2 = -4 + 12.25 Combine like terms: -4 + 12.25 = 8.25 12.25 + -7b + b2 = 8.25 Factor a perfect square on the left side: (b + -3.5)(b + -3.5) = 8.25 Calculate the square root of the right side: 2.872281323 Break this problem into two subproblems by setting (b + -3.5) equal to 2.872281323 and -2.872281323.Subproblem 1
b + -3.5 = 2.872281323 Simplifying b + -3.5 = 2.872281323 Reorder the terms: -3.5 + b = 2.872281323 Solving -3.5 + b = 2.872281323 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + b = 2.872281323 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + b = 2.872281323 + 3.5 b = 2.872281323 + 3.5 Combine like terms: 2.872281323 + 3.5 = 6.372281323 b = 6.372281323 Simplifying b = 6.372281323Subproblem 2
b + -3.5 = -2.872281323 Simplifying b + -3.5 = -2.872281323 Reorder the terms: -3.5 + b = -2.872281323 Solving -3.5 + b = -2.872281323 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + b = -2.872281323 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + b = -2.872281323 + 3.5 b = -2.872281323 + 3.5 Combine like terms: -2.872281323 + 3.5 = 0.627718677 b = 0.627718677 Simplifying b = 0.627718677Solution
The solution to the problem is based on the solutions from the subproblems. b = {6.372281323, 0.627718677}
