Isiah is dividing 2x3 - x2 + 2x + 5 by x + 1 using a division table. His work is shown here. What is the value of A? –5 5 1x 5x

Division tables are used to show the quotients of numbers and expressions.

The value of A is (b) 5

From the division table, we have the following entry in the x row:

x | -3 | A

Multiply -3 and A by x

This gives

From the question, the polynomial function is

The term "2x" has a factor of x.

So, the equation becomes

Add 3x to both sides

Divide both sides by x

Rewrite the equation as

Hence, the value of A is (b) 5

5

Step-by-step explanation:

The computation of the value of A is shown below:

Given that

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

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

Now dividing it by x

So,

x = 5

One more method to check whether it is correct or not

That gives the

Hence the correct option is 2nd i.e 5
