What is remainder when x³ 2x² X 1 is divided by?

Sagot :

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.
