A graph shows the roots to be {-4, 3, 6}.
So you have 8 digits (number available) to form 3 digit numbers (number selected).
Using the formula
where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.
The number of three digit numbers that can be formed =
= 336
<span> O R
