Question

Let $f\left(x\right)=2x^2+3x+1$, the remainder when $f\left(x\right)$ is divisible by $(x+1)$ is

• A. $6$
• B. $0$
• C. $-6$
• D. none of these

Answer 1

The correct option is B $0$

Given, $f\left(x\right)=2x^2+3x+1$.

Now by remainder theorem we have, when $f\left(x\right)$ is divisible by $(x+1)$, then the remainder will be $f(-1)$.

Now,

$f(-1)$ $=2-3+1$ $=0$.

Hence, option $B$ is correct.
