Captain Jessica has a ship, the H.M.S. Khan. The ship is two furlongs from the dread pirate Luis and his merciless band of thiev
es. The Captain has probability 4/9 of hitting the pirate ship. The pirate only has one good eye, so he hits the Captain's ship with probability 1/4 .If both fire their cannons at the same time, what is the probability that both the pirate and the Captain hit each other's ships?
For this case we have the following polynomial: 7x2 + 68xy - 20y2 Factoring we have: (7x-2y) (x + 10y) We verify the factorization: 7x2 + 70xy - 2xy - 20y2 Rewriting we have: 7x2 + 68xy - 20y2 Therefore, the factorization is correct. Answer: A) (7x - 2y) (x + 10y)
