Question

find the remainder when X square + 2 X + 1 is divided by X + 1​

Answer 1

Here, divisor is x+1

so, x+1 = 0

x = (-1)

putting value of x in given p(x)

p(x)

$= ( - 1) {}^{2} + 2(-1) + 1 \\ = 1 - 2 + 1 \\ = 0$

therefore, the value of remainder is 0.

you can find out the remainder by dividing method too.

Hope it helps you!!
