Simplifying b2 + 7b + -25 = 12 Reorder the terms: -25 + 7b + b2 = 12 Solving -25 + 7b + b2 = 12 Solving for variable 'b'. Reorder the terms: -25 + -12 + 7b + b2 = 12 + -12 Combine like terms: -25 + -12 = -37 -37 + 7b + b2 = 12 + -12 Combine like terms: 12 + -12 = 0 -37 + 7b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '37' to each side of the equation. -37 + 7b + 37 + b2 = 0 + 37 Reorder the terms: -37 + 37 + 7b + b2 = 0 + 37 Combine like terms: -37 + 37 = 0 0 + 7b + b2 = 0 + 37 7b + b2 = 0 + 37 Combine like terms: 0 + 37 = 37 7b + b2 = 37 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 = 37 + 12.25 Reorder the terms: 12.25 + 7b + b2 = 37 + 12.25 Combine like terms: 37 + 12.25 = 49.25 12.25 + 7b + b2 = 49.25 Factor a perfect square on the left side: (b + 3.5)(b + 3.5) = 49.25 Calculate the square root of the right side: 7.017834424 Break this problem into two subproblems by setting (b + 3.5) equal to 7.017834424 and -7.017834424.Subproblem 1
b + 3.5 = 7.017834424 Simplifying b + 3.5 = 7.017834424 Reorder the terms: 3.5 + b = 7.017834424 Solving 3.5 + b = 7.017834424 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 = 7.017834424 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + b = 7.017834424 + -3.5 b = 7.017834424 + -3.5 Combine like terms: 7.017834424 + -3.5 = 3.517834424 b = 3.517834424 Simplifying b = 3.517834424Subproblem 2
b + 3.5 = -7.017834424 Simplifying b + 3.5 = -7.017834424 Reorder the terms: 3.5 + b = -7.017834424 Solving 3.5 + b = -7.017834424 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 = -7.017834424 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + b = -7.017834424 + -3.5 b = -7.017834424 + -3.5 Combine like terms: -7.017834424 + -3.5 = -10.517834424 b = -10.517834424 Simplifying b = -10.517834424Solution
The solution to the problem is based on the solutions from the subproblems. b = {3.517834424, -10.517834424}
