Question 157312
I am confused by your answer???

why wasnt the 15 subtracted from the -5?

This was my solution
5x^3-5x+1/x-3

     5x^2+10x31/x-3
x-3 /5x^3-5x+1  
    -5x^3-15 [here you subtracted 15 which should have been 15x^2.
         +10+1  seeing as ther is no x^2 term you bring down the -15x^2]
         -10+30
             +31/x-3

Where did I go wrong?


5x^3-5x+1/x-3

```````5x^2+15x+40

Answer: 5x^2+15x+40 r 121/(x-3)
