Answer :
When x^3−2x^2 +x+1 is divided by (x−1) then remainder is 2.
In the given question, we have to find what is remainder when x^3−2x^2 +x+1 is divided by (x−1).
To find the remainder there are two ways. First we divide the x^3−2x^2 +x+1 by (x−1). Second we find the value of from (x−1) by equating (x−1) equal to zero. The put the value of x in the expression x^3−2x^2 +x+1.
In this we ca easily find the remainder.
Now we firstly find the value of x;
(x−1) = 0
Add 1 on both side we get;
x=1
Now put x=1 in the expression x^3−2x^2 +x+1.
x^3−2x^2 +x+1 = (1)^3−2(1)^2+1+1
x^3−2x^2 +x+1 = 1−2+1+1
x^3−2x^2 +x+1 = 2
Hence, when x^3−2x^2 +x+1 is divided by (x−1) then remainder is 2.
