Simplifying x4 + 2x2 + 81 = 0 Reorder the terms: 81 + 2x2 + x4 = 0 Solving 81 + 2x2 + x4 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-81' to each side of the equation. 81 + 2x2 + -81 + x4 = 0 + -81 Reorder the terms: 81 + -81 + 2x2 + x4 = 0 + -81 Combine like terms: 81 + -81 = 0 0 + 2x2 + x4 = 0 + -81 2x2 + x4 = 0 + -81 Combine like terms: 0 + -81 = -81 2x2 + x4 = -81 The x term is 2x2. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x2 + 1 + x4 = -81 + 1 Reorder the terms: 1 + 2x2 + x4 = -81 + 1 Combine like terms: -81 + 1 = -80 1 + 2x2 + x4 = -80 Factor a perfect square on the left side: (x2 + 1)(x2 + 1) = -80 Can't calculate square root of the right side. The solution to this equation could not be determined.
