Simplifying b + 3 = b * b Reorder the terms: 3 + b = b * b Multiply b * b 3 + b = b2 Solving 3 + b = b2 Solving for variable 'b'. Combine like terms: b2 + -1b2 = 0 3 + b + -1b2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -3 + -1b + b2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + -1b + 3 + b2 = 0 + 3 Reorder the terms: -3 + 3 + -1b + b2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1b + b2 = 0 + 3 -1b + b2 = 0 + 3 Combine like terms: 0 + 3 = 3 -1b + b2 = 3 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. -1b + 0.25 + b2 = 3 + 0.25 Reorder the terms: 0.25 + -1b + b2 = 3 + 0.25 Combine like terms: 3 + 0.25 = 3.25 0.25 + -1b + b2 = 3.25 Factor a perfect square on the left side: (b + 0.5)(b + 0.5) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (b + 0.5) equal to 1.802775638 and -1.802775638.Subproblem 1
b + 0.5 = 1.802775638 Simplifying b + 0.5 = 1.802775638 Reorder the terms: 0.5 + b = 1.802775638 Solving 0.5 + b = 1.802775638 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 = 1.802775638 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + b = 1.802775638 + -0.5 b = 1.802775638 + -0.5 Combine like terms: 1.802775638 + -0.5 = 1.302775638 b = 1.302775638 Simplifying b = 1.302775638Subproblem 2
b + 0.5 = -1.802775638 Simplifying b + 0.5 = -1.802775638 Reorder the terms: 0.5 + b = -1.802775638 Solving 0.5 + b = -1.802775638 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 = -1.802775638 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + b = -1.802775638 + -0.5 b = -1.802775638 + -0.5 Combine like terms: -1.802775638 + -0.5 = -2.302775638 b = -2.302775638 Simplifying b = -2.302775638Solution
The solution to the problem is based on the solutions from the subproblems. b = {1.302775638, -2.302775638}
