Question

When x³-ax²+6x-a is divided by x-1 the remainder is 2 points 7-a 7+a 7-2a 7+2a​

Answer 1

Answer:

Hi friend

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

Your answer

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

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
