Simplifying 8b2 + 7b + 30 = 0 Reorder the terms: 30 + 7b + 8b2 = 0 Solving 30 + 7b + 8b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 3.75 + 0.875b + b2 = 0 Move the constant term to the right: Add '-3.75' to each side of the equation. 3.75 + 0.875b + -3.75 + b2 = 0 + -3.75 Reorder the terms: 3.75 + -3.75 + 0.875b + b2 = 0 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + 0.875b + b2 = 0 + -3.75 0.875b + b2 = 0 + -3.75 Combine like terms: 0 + -3.75 = -3.75 0.875b + b2 = -3.75 The b term is 0.875b. Take half its coefficient (0.4375). Square it (0.19140625) and add it to both sides. Add '0.19140625' to each side of the equation. 0.875b + 0.19140625 + b2 = -3.75 + 0.19140625 Reorder the terms: 0.19140625 + 0.875b + b2 = -3.75 + 0.19140625 Combine like terms: -3.75 + 0.19140625 = -3.55859375 0.19140625 + 0.875b + b2 = -3.55859375 Factor a perfect square on the left side: (b + 0.4375)(b + 0.4375) = -3.55859375 Can't calculate square root of the right side. The solution to this equation could not be determined.
