What divisor is represented by the synthetic division below?   –5 5 x + 5 x – 5

For this case, the dividend is given by:
 
 We note that the following numbers:
 2, 10, 1, 5
 They are the coefficients of the polynomial and they are in the upper part of the division.
 The number -5 is the opposite value of the divisor constant.
 Therefore, the divisor is given by:
 x + 5
 
 The divisor is:
 x + 5
