This is a problem of permutation. In mathematics, the permutation relates to the fact of arranging all the member of a set into order. So, the k permutations of n are the different ordered arrangements of a k element subset of a n set. In the problem above k = 9 are the elements which are all the numerals available. On the other hand, n set is equal to 4. So, the formula of such k-permutations of n is given by:
Solving for k = 9 and n = 4:

Answer:
(x - 6) (x + 1)
x = 6 and x = - 1
Step-by-step explanation:
x^2 - 5x - 6
-6 +1 = -5 and (-6)*(1) = -6
(x - 6) (x + 1)
x -6 = 0
x = 6 and x + 1 = 0
x = -1
