Answer 2

Answer:

The remainder value is -2, when $x^{3}-2 x^{2}-4 x-3$ divided by $x+1.$

Step-by-step explanation:

$x + 1 = 0$

$x = -1$

Given:

$x^{3}-2 x^{2}-4 x-3$

To find:

$\Rightarrow x^{3}-2 x^{2}-4 x-3 \div \mathbf{x}+\mathbf{1}$

Step by Step explanation:

$=x^{3}-2 x^{2}-4 x-3$

$=1^{3}-2(-1)^{2}-4(-1)-3$

$=-1-2+4-3$

Subtract the term,

$=-3+4-3$

$=4-6$

$=-2$

Hence, the remainder value is -2.
