Simplifying x4 + 14x2 + 121 = 0 Reorder the terms: 121 + 14x2 + x4 = 0 Solving 121 + 14x2 + x4 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-121' to each side of the equation. 121 + 14x2 + -121 + x4 = 0 + -121 Reorder the terms: 121 + -121 + 14x2 + x4 = 0 + -121 Combine like terms: 121 + -121 = 0 0 + 14x2 + x4 = 0 + -121 14x2 + x4 = 0 + -121 Combine like terms: 0 + -121 = -121 14x2 + x4 = -121 The x term is 14x2. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x2 + 49 + x4 = -121 + 49 Reorder the terms: 49 + 14x2 + x4 = -121 + 49 Combine like terms: -121 + 49 = -72 49 + 14x2 + x4 = -72 Factor a perfect square on the left side: (x2 + 7)(x2 + 7) = -72 Can't calculate square root of the right side. The solution to this equation could not be determined.
