Answer:
There are NO real solutions to this equation as per the study of its discriminant.
Step-by-step explanation:
In order to answer the question, one needs to examine the "discriminant" associated with this quadratic equation.
Recall that the discriminant of a quadratic equation of the form:
is given by:
in our case :
Then the discriminant becomes:
The discriminant is then a negative number, which means that there are NO real solutions (its solutions must involve imaginary numbers)

Step-by-step explanation:
Given : The number of empty seats in a theater = 9
The number of customers need to find places to sit =6
Since order matters here, so we use permutations
The permutations of n things taking r at a time is given by :-
Then, the number of ways to arrange 6 seat in 9 seats :-
Hence, the number of ways to arrange 6 seat in 9 seats = 60480
