Simplifying 6b2 + 9b + -7 = 0 Reorder the terms: -7 + 9b + 6b2 = 0 Solving -7 + 9b + 6b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. -1.166666667 + 1.5b + b2 = 0 Move the constant term to the right: Add '1.166666667' to each side of the equation. -1.166666667 + 1.5b + 1.166666667 + b2 = 0 + 1.166666667 Reorder the terms: -1.166666667 + 1.166666667 + 1.5b + b2 = 0 + 1.166666667 Combine like terms: -1.166666667 + 1.166666667 = 0.000000000 0.000000000 + 1.5b + b2 = 0 + 1.166666667 1.5b + b2 = 0 + 1.166666667 Combine like terms: 0 + 1.166666667 = 1.166666667 1.5b + b2 = 1.166666667 The b term is 1.5b. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5b + 0.5625 + b2 = 1.166666667 + 0.5625 Reorder the terms: 0.5625 + 1.5b + b2 = 1.166666667 + 0.5625 Combine like terms: 1.166666667 + 0.5625 = 1.729166667 0.5625 + 1.5b + b2 = 1.729166667 Factor a perfect square on the left side: (b + 0.75)(b + 0.75) = 1.729166667 Calculate the square root of the right side: 1.31497782 Break this problem into two subproblems by setting (b + 0.75) equal to 1.31497782 and -1.31497782.Subproblem 1
b + 0.75 = 1.31497782 Simplifying b + 0.75 = 1.31497782 Reorder the terms: 0.75 + b = 1.31497782 Solving 0.75 + b = 1.31497782 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + b = 1.31497782 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + b = 1.31497782 + -0.75 b = 1.31497782 + -0.75 Combine like terms: 1.31497782 + -0.75 = 0.56497782 b = 0.56497782 Simplifying b = 0.56497782Subproblem 2
b + 0.75 = -1.31497782 Simplifying b + 0.75 = -1.31497782 Reorder the terms: 0.75 + b = -1.31497782 Solving 0.75 + b = -1.31497782 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + b = -1.31497782 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + b = -1.31497782 + -0.75 b = -1.31497782 + -0.75 Combine like terms: -1.31497782 + -0.75 = -2.06497782 b = -2.06497782 Simplifying b = -2.06497782Solution
The solution to the problem is based on the solutions from the subproblems. b = {0.56497782, -2.06497782}
