Simplifying b2 + 2b + 13 = 0 Reorder the terms: 13 + 2b + b2 = 0 Solving 13 + 2b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + 2b + -13 + b2 = 0 + -13 Reorder the terms: 13 + -13 + 2b + b2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 2b + b2 = 0 + -13 2b + b2 = 0 + -13 Combine like terms: 0 + -13 = -13 2b + b2 = -13 The b term is 2b. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2b + 1 + b2 = -13 + 1 Reorder the terms: 1 + 2b + b2 = -13 + 1 Combine like terms: -13 + 1 = -12 1 + 2b + b2 = -12 Factor a perfect square on the left side: (b + 1)(b + 1) = -12 Can't calculate square root of the right side. The solution to this equation could not be determined.
