Simplifying -10b2 + b = -7 Reorder the terms: b + -10b2 = -7 Solving b + -10b2 = -7 Solving for variable 'b'. Reorder the terms: 7 + b + -10b2 = -7 + 7 Combine like terms: -7 + 7 = 0 7 + b + -10b2 = 0 Begin completing the square. Divide all terms by -10 the coefficient of the squared term: Divide each side by '-10'. -0.7 + -0.1b + b2 = 0 Move the constant term to the right: Add '0.7' to each side of the equation. -0.7 + -0.1b + 0.7 + b2 = 0 + 0.7 Reorder the terms: -0.7 + 0.7 + -0.1b + b2 = 0 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + -0.1b + b2 = 0 + 0.7 -0.1b + b2 = 0 + 0.7 Combine like terms: 0 + 0.7 = 0.7 -0.1b + b2 = 0.7 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. -0.1b + 0.25 + b2 = 0.7 + 0.25 Reorder the terms: 0.25 + -0.1b + b2 = 0.7 + 0.25 Combine like terms: 0.7 + 0.25 = 0.95 0.25 + -0.1b + b2 = 0.95 Factor a perfect square on the left side: (b + 0.5)(b + 0.5) = 0.95 Calculate the square root of the right side: 0.974679434 Break this problem into two subproblems by setting (b + 0.5) equal to 0.974679434 and -0.974679434.Subproblem 1
b + 0.5 = 0.974679434 Simplifying b + 0.5 = 0.974679434 Reorder the terms: 0.5 + b = 0.974679434 Solving 0.5 + b = 0.974679434 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 = 0.974679434 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + b = 0.974679434 + -0.5 b = 0.974679434 + -0.5 Combine like terms: 0.974679434 + -0.5 = 0.474679434 b = 0.474679434 Simplifying b = 0.474679434Subproblem 2
b + 0.5 = -0.974679434 Simplifying b + 0.5 = -0.974679434 Reorder the terms: 0.5 + b = -0.974679434 Solving 0.5 + b = -0.974679434 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 = -0.974679434 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + b = -0.974679434 + -0.5 b = -0.974679434 + -0.5 Combine like terms: -0.974679434 + -0.5 = -1.474679434 b = -1.474679434 Simplifying b = -1.474679434Solution
The solution to the problem is based on the solutions from the subproblems. b = {0.474679434, -1.474679434}
