Question

2 Find the remainder when x^3-ax ^2 + 6 x - a is
divided by x - a​

Answer 1

Answer:

So, by the Remainder Theorem, 2a3+5a is the remainder when x3+ax2+6x−a is divided by x−a.

Step-by-step explanation:

Correct option is

A

a

C

5a

Here, p(x)=x3+ax2+6x−a, and the zero of x−a is a

So, p(a)=a3+a×a2+6×a−a

                =2a3+5a

               So, by the Remainder Theorem, 2a3+5a is the remainder when x3+ax2+6x−a is divided by x−a.
