Answer 2

Answer:

5

Step-by-step explanation:

The computation of the value of A is shown below:

Given that

$2x^3 - x^2 + 2x + 5$

i.e divided by x + 1

As we know that the total of -3x and (A)x must be equivalent to the third term of the initial polynomial which is 2x. It is given below

$-3x+(A)x=2x$

Now if we add 3x to  both sides of the equation so

$(A)x=5x$

Now dividing it by x

So,

x = 5

One more method to check whether it is correct or not

$(x+1)(2x^{2}-3x+5)$

That gives the

$2x^{3}-x^{2}+2x+5$

Hence the correct option is 2nd i.e 5
