• A) \(32 t ^ { 5 } - 80 t ^ { 4 } s + 80 t ^ { 3 } s ^ { 2 } - 40 t ^ { 2 } s ^ { 3 } + 10 t s ^ { 4 } - s ^ { 5 }\)
• B) \(32 t ^ { 5 } + 80 t ^ { 4 } s + 80 t ^ { 3 } s ^ { 2 } - 40 t ^ { 2 } s ^ { 3 } + 10 t s ^ { 4 } - s ^ { 5 }\)
• C) \(32 t ^ { 5 } - 80 t ^ { 4 } s - 80 t ^ { 3 } s ^ { 2 } - 40 t ^ { 2 } s ^ { 3 } + 10 t s ^ { 4 } - s ^ { 5 }\)
• D) \(32 t ^ { 5 } - 80 t ^ { 4 } s + 80 t ^ { 3 } s ^ { 2 } + 40 t ^ { 2 } s ^ { 3 } + 10 t s ^ { 4 } + s ^ { 5 }\)
• E) \(32 t ^ { 5 } + 80 t ^ { 4 } s - 80 t ^ { 3 } s ^ { 2 } + 40 t ^ { 2 } s ^ { 3 } - 10 t s ^ { 4 } + s ^ { 5 }\)
