Find the remainder using remainder theorem, when

4x3 – 12x2 + 11x – 5 is divided by 2x – 1

Answer :

4x3 – 12x2 + 11x – 5 is divided by 2x – 1


Remainder theorem states that if p(x) is any polynomial and a is any real number and If p(x) is divided by the linear polynomial (x – a) , then the remainder is p(a).


Let p(x) = 4x3 – 12x2 + 11x – 5 and we have (2x – 1)


The zero of (2x – 1) is


Now using Remainder theorem,


p(x) = 4x3 – 12x2 + 11x – 5 is divided by 2x – 1 then, is the remainder









Remainder = –2
