What divisor is represented by the synthetic division below? 
-5, 5, x + 5, x - 5.

Solution:

The dividend given here is

2x³ + 10x² + x + 5

We see that the numbers

2, 10, 1, and 5 are the coefficients of the polynomial and are on the upper side of the division.

-5 is the opposite of the divisor constant.

So the divisor is written as

x + 5

Therefore, the divisor is x + 5.

What divisor is represented by the synthetic division below?

Summary:

The divisor represented by the synthetic division below is x + 5.
