Simplifying b2 + 8b + 18 = 0 Reorder the terms: 18 + 8b + b2 = 0 Solving 18 + 8b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + 8b + -18 + b2 = 0 + -18 Reorder the terms: 18 + -18 + 8b + b2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + 8b + b2 = 0 + -18 8b + b2 = 0 + -18 Combine like terms: 0 + -18 = -18 8b + b2 = -18 The b term is 8b. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8b + 16 + b2 = -18 + 16 Reorder the terms: 16 + 8b + b2 = -18 + 16 Combine like terms: -18 + 16 = -2 16 + 8b + b2 = -2 Factor a perfect square on the left side: (b + 4)(b + 4) = -2 Can't calculate square root of the right side. The solution to this equation could not be determined.
