Step-by-step explanation:
Consider the given equation
Factor form of a parabola: It displays the x-intercepts.
.... (1)
where, a is a constant and, p and q are x-intercepts.
So, we need to find the factored form of the given equation.
Splinting the middle term we get
.... (2)
On comparing (1) and (2) we get
It means x-intercepts of the given parabola are 4 and 2.
Therefore, equivalent forms of the equation is y=(x-4)(x-2).

Answer:
The correct option is a) n(n-4).
Step-by-step explanation:
Consider the provided information.
Let n represents the number of rows.
The number of seats in each row is 4 less than the number of rows.
This can be written as:
A theater has n rows of seats.
Therefore the total number of seats in the theater is:
Hence, the correct option is a) n(n-4).
