What is remainder when x³ 3x² 3x 1 is divided by x 1?

Sagot :

When x^3+3x^2+3x+1 is divided by (x+1) then remainder is 0.

In the given question, we have to find what is remainder when x^3+3x^2+3x+1 is divided by (x+1).

To find the remainder there are two ways. First we divide the x^3+3x^2+3x+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+3x^2+3x+1.

In this we ca easily find the remainder.

Now we firstly find the value of x;

(x+1) = 0

Subtract 1 on both side we get;

x= −1

Now put x=-1 in the expression x^3+3x^2+3x+1.

x^3+3x^2+3x+1 = (−1)^3+3(−1)^2+3(−1)+1

x^3+3x^2+3x+1 = −1+3−3+1

x^3+3x^2+3x+1 = 0

Hence, when x^3+3x^2+3x+1 is divided by (x+1) then remainder is 0.
