Simplifying x4 + x2 + 8 = 0 Reorder the terms: 8 + x2 + x4 = 0 Solving 8 + x2 + x4 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + x2 + -8 + x4 = 0 + -8 Reorder the terms: 8 + -8 + x2 + x4 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + x2 + x4 = 0 + -8 x2 + x4 = 0 + -8 Combine like terms: 0 + -8 = -8 x2 + x4 = -8 The x term is x2. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x2 + 0.25 + x4 = -8 + 0.25 Reorder the terms: 0.25 + x2 + x4 = -8 + 0.25 Combine like terms: -8 + 0.25 = -7.75 0.25 + x2 + x4 = -7.75 Factor a perfect square on the left side: (x2 + 0.5)(x2 + 0.5) = -7.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
