Create a quadratic polynomial function f(x) and a linear binomial in the form (x − a).
erik [133]
Quadratic polynomial  x^2 - x - 6 = f(x)
binomial  (x-3)

dividing:-
                x   + 2
          ----------------------
x - 3   )  x^2  - x   -  6
             x^2 - 3x
             ----------
                     2x - 6
                     2x - 6
                     --------
                      .........

result of division is (x + 2)  
s o we can write the function as (x - 3)(x + 2)

Part 2  f(a)  = f(3)   =  (3)^2 - 3 - 6 = 0

Part3  The remainder Theorem  states that  the remainder when a polynomial is divided by (x - a)  then the remainder is f(a).  If f(a) = 0 then  x - a is a factor.
In the above case f(3) = 0 therefore (x - 3) is a factor of our polynomial.

At the local ball park, the team charges $5 for each ticket and expects to make $1,400 in concessions. The team must pay its pla
Eduardwww [97]

Answer:

The number of tickets must be sold is 2500

Step-by-step explanation:

The charge for each ticket = $ 5

The concessions amount =  $ 1400

The amount paid to players = $ 2000

The amount paid to workers = $ 1600

The cost of each bag given to each fan = $ 3 per bag

Let The number of tickets sold = x

Now, number of ticket sold = number of fans = x

So, According to question

( charge per ticket × number of fans - cost of each bag × number of fan - concession amount ) =  amount paid to players + amount paid to workers

Or, $5 x - $3 x - $1400 = $2000 + $1600

Or, $2 x = $3600 + $1400

Or, $2 x = $5000

∴         x = \frac{5000}{2} = 2500

Hence  Answer
