Question

.Using remainder theorem, find the remainder when x4 – 3x3 + 2x2+ x -1 is divided by (x-2)

Answer 1

I hope it will help

Step-by-step explanation:

Let f(x)=x^4-3x^3+2x^2+x-1

let g(x)=x-2

The zero of g(x) is

g(x)=0

x-2=0

x=2

So by remainder theorem

f(2)= (2)^4-3.(2)^3+2(2)^2+2-1

=16-24+8+2-1

=1
