Simplifying x2 + 8x + 31 = 0 Reorder the terms: 31 + 8x + x2 = 0 Solving 31 + 8x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-31' to each side of the equation. 31 + 8x + -31 + x2 = 0 + -31 Reorder the terms: 31 + -31 + 8x + x2 = 0 + -31 Combine like terms: 31 + -31 = 0 0 + 8x + x2 = 0 + -31 8x + x2 = 0 + -31 Combine like terms: 0 + -31 = -31 8x + x2 = -31 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = -31 + 16 Reorder the terms: 16 + 8x + x2 = -31 + 16 Combine like terms: -31 + 16 = -15 16 + 8x + x2 = -15 Factor a perfect square on the left side: (x + 4)(x + 4) = -15 Can't calculate square root of the right side. The solution to this equation could not be determined.
