Question

what is the remainder when 2x2+ 3x+1 is divided by x+1​

Answer 1

Answer:

The remainder when $p(x)=2x^2+ 3x+1$ is divided by $x+1$ is 6.

Step-by-step explanation:

For finding the remainder, we need to use remainder theorem.

Let $p(x)=2x^2+ 3x+1$

Hence, to find the remainder on dividing by $x−1$, we need to equate it to 0 and put that value of x in $p(x)$.

$x-1=0\\ \\ x=1\\ \\ p(1)=2(1)^2+3(1)+1\\ \\ p(1)=2+3+1=\\ \\ p(1)=6$
