Simplifying 2b2 + -1b + -30 = 0 Reorder the terms: -30 + -1b + 2b2 = 0 Solving -30 + -1b + 2b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -15 + -0.5b + b2 = 0 Move the constant term to the right: Add '15' to each side of the equation. -15 + -0.5b + 15 + b2 = 0 + 15 Reorder the terms: -15 + 15 + -0.5b + b2 = 0 + 15 Combine like terms: -15 + 15 = 0 0 + -0.5b + b2 = 0 + 15 -0.5b + b2 = 0 + 15 Combine like terms: 0 + 15 = 15 -0.5b + b2 = 15 The b term is -0.5b. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5b + 0.0625 + b2 = 15 + 0.0625 Reorder the terms: 0.0625 + -0.5b + b2 = 15 + 0.0625 Combine like terms: 15 + 0.0625 = 15.0625 0.0625 + -0.5b + b2 = 15.0625 Factor a perfect square on the left side: (b + -0.25)(b + -0.25) = 15.0625 Calculate the square root of the right side: 3.881043674 Break this problem into two subproblems by setting (b + -0.25) equal to 3.881043674 and -3.881043674.Subproblem 1
b + -0.25 = 3.881043674 Simplifying b + -0.25 = 3.881043674 Reorder the terms: -0.25 + b = 3.881043674 Solving -0.25 + b = 3.881043674 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + b = 3.881043674 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + b = 3.881043674 + 0.25 b = 3.881043674 + 0.25 Combine like terms: 3.881043674 + 0.25 = 4.131043674 b = 4.131043674 Simplifying b = 4.131043674Subproblem 2
b + -0.25 = -3.881043674 Simplifying b + -0.25 = -3.881043674 Reorder the terms: -0.25 + b = -3.881043674 Solving -0.25 + b = -3.881043674 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + b = -3.881043674 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + b = -3.881043674 + 0.25 b = -3.881043674 + 0.25 Combine like terms: -3.881043674 + 0.25 = -3.631043674 b = -3.631043674 Simplifying b = -3.631043674Solution
The solution to the problem is based on the solutions from the subproblems. b = {4.131043674, -3.631043674}
