• A) \(\quad \frac { 1 } { 8 } x ^ { 4 } + \frac { 1 } { 2 } x ^ { 3 } d + \frac { 3 } { 2 } x ^ { 2 } d ^ { 2 } + 2 x d ^ { 3 } + d ^ { 4 }\)
• B) \(\quad \frac { 1 } { 16 } x ^ { 4 } + \frac { 1 } { 8 } x ^ { 3 } d + \frac { 1 } { 4 } x ^ { 2 } d ^ { 2 } + \frac { 1 } { 2 } x d ^ { 3 } + d ^ { 4 }\)
• C) \(\quad \frac { 1 } { 16 } x ^ { 4 } + \frac { 1 } { 2 } x ^ { 3 } d + \frac { 3 } { 2 } x ^ { 2 } d ^ { 2 } + 2 x d ^ { 3 } + d ^ { 4 }\)
• D) \(\quad x ^ { 4 } + x ^ { 3 } d + x ^ { 2 } d ^ { 2 } + x d ^ { 3 } + d ^ { 4 }\)
• E) \(\quad \frac { 1 } { 2 } x ^ { 4 } + d ^ { 4 }\)
