Simplifying x2 + 18x + 108 = 0 Reorder the terms: 108 + 18x + x2 = 0 Solving 108 + 18x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-108' to each side of the equation. 108 + 18x + -108 + x2 = 0 + -108 Reorder the terms: 108 + -108 + 18x + x2 = 0 + -108 Combine like terms: 108 + -108 = 0 0 + 18x + x2 = 0 + -108 18x + x2 = 0 + -108 Combine like terms: 0 + -108 = -108 18x + x2 = -108 The x term is 18x. Take half its coefficient (9). Square it (81) and add it to both sides. Add '81' to each side of the equation. 18x + 81 + x2 = -108 + 81 Reorder the terms: 81 + 18x + x2 = -108 + 81 Combine like terms: -108 + 81 = -27 81 + 18x + x2 = -27 Factor a perfect square on the left side: (x + 9)(x + 9) = -27 Can't calculate square root of the right side. The solution to this equation could not be determined.
