Simplifying x2 + 6x + 57 = 0 Reorder the terms: 57 + 6x + x2 = 0 Solving 57 + 6x + 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 + 6x + -57 + x2 = 0 + -57 Reorder the terms: 57 + -57 + 6x + x2 = 0 + -57 Combine like terms: 57 + -57 = 0 0 + 6x + x2 = 0 + -57 6x + x2 = 0 + -57 Combine like terms: 0 + -57 = -57 6x + x2 = -57 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = -57 + 9 Reorder the terms: 9 + 6x + x2 = -57 + 9 Combine like terms: -57 + 9 = -48 9 + 6x + x2 = -48 Factor a perfect square on the left side: (x + 3)(x + 3) = -48 Can't calculate square root of the right side. The solution to this equation could not be determined.
