Simplifying x4 + -16x2 + 65 = 0 Reorder the terms: 65 + -16x2 + x4 = 0 Solving 65 + -16x2 + x4 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-65' to each side of the equation. 65 + -16x2 + -65 + x4 = 0 + -65 Reorder the terms: 65 + -65 + -16x2 + x4 = 0 + -65 Combine like terms: 65 + -65 = 0 0 + -16x2 + x4 = 0 + -65 -16x2 + x4 = 0 + -65 Combine like terms: 0 + -65 = -65 -16x2 + x4 = -65 The x term is -16x2. Take half its coefficient (-8). Square it (64) and add it to both sides. Add '64' to each side of the equation. -16x2 + 64 + x4 = -65 + 64 Reorder the terms: 64 + -16x2 + x4 = -65 + 64 Combine like terms: -65 + 64 = -1 64 + -16x2 + x4 = -1 Factor a perfect square on the left side: (x2 + -8)(x2 + -8) = -1 Can't calculate square root of the right side. The solution to this equation could not be determined.
