ab⁵-b⁵-ab³+b³ = b⁵(a-1)-b³(a-1) = (b⁵-b³)(a-1) = b³(b²-1)(a-1) = b³(b-1)(b+1)(a-1)

WHY THE CAT IS ALWAYS IN THE KITCHEN A little grey cat lives in the forest. She is very weak and she is afraid of the forest. The cat is afraid of many animals and birds. So she wants to have a good friend who will protect her. Suddenly she sees a fox and thinks, "This must be the strongest animal, I shall follow him and he will protect me." And the cat follows the fox. But then a lion comes and the fox runs away. He is afraid of the lion. The cat looks at the lion and thinks, "This must be the strongest animal. Even the fox is afraid of him. So I will follow the lion and he will protect me." And the cat follows the lion. When the animals and the birds see the lion, they all run away as quicklyas they can. They are afraid of the lion. And the cat thinks, "Yes, the lion is the strongest animal. All the animals and the birds are afraid of him. The lion will protect me." 35 Then a man with a gun comes to the forest and the lion runs away from the man. The cat looks at the man and thinks, "The man is stronger than the lion. He can kill the lion. I will follow him and he will protect me." So the cat follows the man and comes to his house.When they come home, thcy see a woman.
