Simplifying x2 + 7x + 27 = 0 Reorder the terms: 27 + 7x + x2 = 0 Solving 27 + 7x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-27' to each side of the equation. 27 + 7x + -27 + x2 = 0 + -27 Reorder the terms: 27 + -27 + 7x + x2 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + 7x + x2 = 0 + -27 7x + x2 = 0 + -27 Combine like terms: 0 + -27 = -27 7x + x2 = -27 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = -27 + 12.25 Reorder the terms: 12.25 + 7x + x2 = -27 + 12.25 Combine like terms: -27 + 12.25 = -14.75 12.25 + 7x + x2 = -14.75 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = -14.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
