Simplifying x4 + 6x2 + 13 = 0 Reorder the terms: 13 + 6x2 + x4 = 0 Solving 13 + 6x2 + x4 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + 6x2 + -13 + x4 = 0 + -13 Reorder the terms: 13 + -13 + 6x2 + x4 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 6x2 + x4 = 0 + -13 6x2 + x4 = 0 + -13 Combine like terms: 0 + -13 = -13 6x2 + x4 = -13 The x term is 6x2. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x2 + 9 + x4 = -13 + 9 Reorder the terms: 9 + 6x2 + x4 = -13 + 9 Combine like terms: -13 + 9 = -4 9 + 6x2 + x4 = -4 Factor a perfect square on the left side: (x2 + 3)(x2 + 3) = -4 Can't calculate square root of the right side. The solution to this equation could not be determined.
