Simplifying x2 + 6x + 135 = 0 Reorder the terms: 135 + 6x + x2 = 0 Solving 135 + 6x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-135' to each side of the equation. 135 + 6x + -135 + x2 = 0 + -135 Reorder the terms: 135 + -135 + 6x + x2 = 0 + -135 Combine like terms: 135 + -135 = 0 0 + 6x + x2 = 0 + -135 6x + x2 = 0 + -135 Combine like terms: 0 + -135 = -135 6x + x2 = -135 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 = -135 + 9 Reorder the terms: 9 + 6x + x2 = -135 + 9 Combine like terms: -135 + 9 = -126 9 + 6x + x2 = -126 Factor a perfect square on the left side: (x + 3)(x + 3) = -126 Can't calculate square root of the right side. The solution to this equation could not be determined.
