Question

if the polynomial x^3-ax^2+2x-a is divided (x-a), then remainder is

Answer 1

this is the ans by remainder theorem

Answer 2

If a polynomial $f(x)$ is divided by $x-a$ then the remainder is $f(a)$. Here, $f(x)=x^3-ax^2+2x-a$.

The remainder when divided by $x-a$ is

$f(a)=a^3-a.a^2+2a-a\\ f(a)=a$
