For the first picking the probability of picking a is 1/26 as there is only 1 a out of the 26 letters. For the second picking there are only 25 letters and there is only 1 e out of the letters. For the succeeding picks, the probabilities are 1/24, 1/23, and 1/22. Thus, the probability is 1/7893600.
8x²-18xy-5y²
8x²+2xy-20xy-5y²
2x(4x+y) -5y (4x+y)
= (2x-5y) (4x+y)
