Simplifying x2 + 8 = -4x Reorder the terms: 8 + x2 = -4x Solving 8 + x2 = -4x Solving for variable 'x'. Reorder the terms: 8 + 4x + x2 = -4x + 4x Combine like terms: -4x + 4x = 0 8 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + 4x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + 4x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 4x + x2 = 0 + -8 4x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 4x + x2 = -8 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 = -8 + 4 Reorder the terms: 4 + 4x + x2 = -8 + 4 Combine like terms: -8 + 4 = -4 4 + 4x + x2 = -4 Factor a perfect square on the left side: (x + 2)(x + 2) = -4 Can't calculate square root of the right side. The solution to this equation could not be determined.
