Simplifying x2 + 6x + 55 = 0 Reorder the terms: 55 + 6x + x2 = 0 Solving 55 + 6x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-55' to each side of the equation. 55 + 6x + -55 + x2 = 0 + -55 Reorder the terms: 55 + -55 + 6x + x2 = 0 + -55 Combine like terms: 55 + -55 = 0 0 + 6x + x2 = 0 + -55 6x + x2 = 0 + -55 Combine like terms: 0 + -55 = -55 6x + x2 = -55 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 = -55 + 9 Reorder the terms: 9 + 6x + x2 = -55 + 9 Combine like terms: -55 + 9 = -46 9 + 6x + x2 = -46 Factor a perfect square on the left side: (x + 3)(x + 3) = -46 Can't calculate square root of the right side. The solution to this equation could not be determined.
