Question

Using the remainder theorem, find the remainder, when p(x) is divided by g(x), where
(px)=x3ax2+6xa,g(x)=xa

Open in App
Solution

p(x)=x3ax2+6xag(x)=xa

By remainder theorem, when p(x) is divided by ( x-a), then the remainder = p(a).

Putting x = a in p(x), we get

p(a)=(a)3a(a)2+6(a)aa3a3+6aa=5a

∴ Remainder = 5a

Thus, the remainder when p(x) is divided by g(x) is 5a.
