Answer: 

Step-by-step explanation: Given expression (x^3-x^2-17x-15)/(x-5).
We need to divide it x^3-x^2-17x-15 by x-5 using synthetic division .
In order to solve by synthetic division, we would write all the coefficients of given divisor polynomial:
And we divide them by 5 using synthetic division method.
 ______________ 
 5 | 1 -1 -17 -15 Getting first number down.
 | 5 20 -15 Multiplying each down number by 
 - - - - - - - - - - - - - - - - divisor 5. 
 1 4 3 0 5×1=5 , 5×2=20, 5×2=15
 Subtracting those products from coefficients.
Now, writing the final polynomial degree 1 less than 3, that is 2.
So, 
 would be our quotient.
 would be our quotient.
