Create a quadratic polynomial function f(x) and a linear binomial in the form (x − a).

part 1. show all work using long division to divide your polynomial by the binomial.

part 2. show all work to evaluate f(a) using the function you created.

part 3. use complete sentences to explain how the remainder theorem is used to determine whether your linear binomial is a factor of your polynomial function

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.

I’m confused this is what i’m doing in class but the question is confusing
