Answer:

yes

Step-by-step explanation:

Dividing :  x3-6x2-x+30

                             ("Dividend")

By         :    x-5    ("Divisor")

dividend     x3  -  6x2  -  x  +  30

- divisor  * x2     x3  -  5x2        

remainder      -  x2  -  x  +  30

- divisor  * -x1      -  x2  +  5x    

remainder          -  6x  +  30

- divisor  * -6x0          -  6x  +  30

remainder                0

Quotient :  x2-x-6  Remainder:  0
