Simplifying 30 + b2 + b = 0 Reorder the terms: 30 + b + b2 = 0 Solving 30 + b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-30' to each side of the equation. 30 + b + -30 + b2 = 0 + -30 Reorder the terms: 30 + -30 + b + b2 = 0 + -30 Combine like terms: 30 + -30 = 0 0 + b + b2 = 0 + -30 b + b2 = 0 + -30 Combine like terms: 0 + -30 = -30 b + b2 = -30 The b term is b. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. b + 0.25 + b2 = -30 + 0.25 Reorder the terms: 0.25 + b + b2 = -30 + 0.25 Combine like terms: -30 + 0.25 = -29.75 0.25 + b + b2 = -29.75 Factor a perfect square on the left side: (b + 0.5)(b + 0.5) = -29.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
