Simplifying x2 + 12x + 57 = 0 Reorder the terms: 57 + 12x + x2 = 0 Solving 57 + 12x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-57' to each side of the equation. 57 + 12x + -57 + x2 = 0 + -57 Reorder the terms: 57 + -57 + 12x + x2 = 0 + -57 Combine like terms: 57 + -57 = 0 0 + 12x + x2 = 0 + -57 12x + x2 = 0 + -57 Combine like terms: 0 + -57 = -57 12x + x2 = -57 The x term is 12x. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12x + 36 + x2 = -57 + 36 Reorder the terms: 36 + 12x + x2 = -57 + 36 Combine like terms: -57 + 36 = -21 36 + 12x + x2 = -21 Factor a perfect square on the left side: (x + 6)(x + 6) = -21 Can't calculate square root of the right side. The solution to this equation could not be determined.
