Simplifying 35b2 + b = 1 Reorder the terms: b + 35b2 = 1 Solving b + 35b2 = 1 Solving for variable 'b'. Reorder the terms: -1 + b + 35b2 = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + b + 35b2 = 0 Begin completing the square. Divide all terms by 35 the coefficient of the squared term: Divide each side by '35'. -0.02857142857 + 0.02857142857b + b2 = 0 Move the constant term to the right: Add '0.02857142857' to each side of the equation. -0.02857142857 + 0.02857142857b + 0.02857142857 + b2 = 0 + 0.02857142857 Reorder the terms: -0.02857142857 + 0.02857142857 + 0.02857142857b + b2 = 0 + 0.02857142857 Combine like terms: -0.02857142857 + 0.02857142857 = 0.00000000000 0.00000000000 + 0.02857142857b + b2 = 0 + 0.02857142857 0.02857142857b + b2 = 0 + 0.02857142857 Combine like terms: 0 + 0.02857142857 = 0.02857142857 0.02857142857b + b2 = 0.02857142857 The b term is b. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.02857142857b + 0.25 + b2 = 0.02857142857 + 0.25 Reorder the terms: 0.25 + 0.02857142857b + b2 = 0.02857142857 + 0.25 Combine like terms: 0.02857142857 + 0.25 = 0.27857142857 0.25 + 0.02857142857b + b2 = 0.27857142857 Factor a perfect square on the left side: (b + 0.5)(b + 0.5) = 0.27857142857 Calculate the square root of the right side: 0.527798663 Break this problem into two subproblems by setting (b + 0.5) equal to 0.527798663 and -0.527798663.Subproblem 1
b + 0.5 = 0.527798663 Simplifying b + 0.5 = 0.527798663 Reorder the terms: 0.5 + b = 0.527798663 Solving 0.5 + b = 0.527798663 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + b = 0.527798663 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + b = 0.527798663 + -0.5 b = 0.527798663 + -0.5 Combine like terms: 0.527798663 + -0.5 = 0.027798663 b = 0.027798663 Simplifying b = 0.027798663Subproblem 2
b + 0.5 = -0.527798663 Simplifying b + 0.5 = -0.527798663 Reorder the terms: 0.5 + b = -0.527798663 Solving 0.5 + b = -0.527798663 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + b = -0.527798663 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + b = -0.527798663 + -0.5 b = -0.527798663 + -0.5 Combine like terms: -0.527798663 + -0.5 = -1.027798663 b = -1.027798663 Simplifying b = -1.027798663Solution
The solution to the problem is based on the solutions from the subproblems. b = {0.027798663, -1.027798663}
