Find the remainder when 9x3 – 3x2 + x – 5 is divided by

Answer :

Let p(x) = 9x3 – 3x2 + x – 5


As we know by Remainder Theorem,


If a polynomial p(x) is divided by a linear polynomial (x – a) then, the remainder is p(a)


Remainder of p(x) when divided by is




Remainder of 9x3 – 3x2 + x – 5 when divided by is –3
