Question

Find the remainder when x³-ax²+3x+1 is divided by x-a​

Answer 1

Answer:

Step-by-step explanation:

Let f(x) = x³ - ax² + 6x - a

So,

------

When,

-----------

f(a) = x³ - ax² + 6x - a

=> (a)³ - a×(a)² + 6×a - a

=> a³ - a³ + 6a - a

=> 5a

Therefore,

------------------

Remainder = 5a
