Simplifying 30b2 + 75b + 46 = 0 Reorder the terms: 46 + 75b + 30b2 = 0 Solving 46 + 75b + 30b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 30 the coefficient of the squared term: Divide each side by '30'. 1.533333333 + 2.5b + b2 = 0 Move the constant term to the right: Add '-1.533333333' to each side of the equation. 1.533333333 + 2.5b + -1.533333333 + b2 = 0 + -1.533333333 Reorder the terms: 1.533333333 + -1.533333333 + 2.5b + b2 = 0 + -1.533333333 Combine like terms: 1.533333333 + -1.533333333 = 0.000000000 0.000000000 + 2.5b + b2 = 0 + -1.533333333 2.5b + b2 = 0 + -1.533333333 Combine like terms: 0 + -1.533333333 = -1.533333333 2.5b + b2 = -1.533333333 The b term is 2.5b. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5b + 1.5625 + b2 = -1.533333333 + 1.5625 Reorder the terms: 1.5625 + 2.5b + b2 = -1.533333333 + 1.5625 Combine like terms: -1.533333333 + 1.5625 = 0.029166667 1.5625 + 2.5b + b2 = 0.029166667 Factor a perfect square on the left side: (b + 1.25)(b + 1.25) = 0.029166667 Calculate the square root of the right side: 0.170782514 Break this problem into two subproblems by setting (b + 1.25) equal to 0.170782514 and -0.170782514.Subproblem 1
b + 1.25 = 0.170782514 Simplifying b + 1.25 = 0.170782514 Reorder the terms: 1.25 + b = 0.170782514 Solving 1.25 + b = 0.170782514 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + b = 0.170782514 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + b = 0.170782514 + -1.25 b = 0.170782514 + -1.25 Combine like terms: 0.170782514 + -1.25 = -1.079217486 b = -1.079217486 Simplifying b = -1.079217486Subproblem 2
b + 1.25 = -0.170782514 Simplifying b + 1.25 = -0.170782514 Reorder the terms: 1.25 + b = -0.170782514 Solving 1.25 + b = -0.170782514 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + b = -0.170782514 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + b = -0.170782514 + -1.25 b = -0.170782514 + -1.25 Combine like terms: -0.170782514 + -1.25 = -1.420782514 b = -1.420782514 Simplifying b = -1.420782514Solution
