Simplifying x2 + 4x + 135 = 0 Reorder the terms: 135 + 4x + x2 = 0 Solving 135 + 4x + 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 + 4x + -135 + x2 = 0 + -135 Reorder the terms: 135 + -135 + 4x + x2 = 0 + -135 Combine like terms: 135 + -135 = 0 0 + 4x + x2 = 0 + -135 4x + x2 = 0 + -135 Combine like terms: 0 + -135 = -135 4x + x2 = -135 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = -135 + 4 Reorder the terms: 4 + 4x + x2 = -135 + 4 Combine like terms: -135 + 4 = -131 4 + 4x + x2 = -131 Factor a perfect square on the left side: (x + 2)(x + 2) = -131 Can't calculate square root of the right side. The solution to this equation could not be determined.
