Question

find the remainder when p(x) = x^3 -9x^2 -ax-a when it is divided by f(X) =x-a ​

Answer 1

Step-by-step explanation:

Let p(x)=a

3

+ax

2

+2x−a and

g(x)=x−a

=>x−a=0

=>x=a

The remainder when p(x) is divided by g(x) is p(3) (By Remainder Theorem)

Thus, p(a)=a

3

−a(a)

2

+2(a)−a

=a

3

−a

3

+2a−a

=a

Therefore,

Remainder=a
