1. UnkleRhaukus

did you use long division, or something else?

7. anonymous

8. anonymous

Actually no. I['m not sure what to do with a single y.

now can you do the next step? (sorry about that)

12. anonymous

that's ok. the next line is y^2 and y (below y^2 and 4y) which subtracts to 3y? then drop the - 5 next to it.

13. UnkleRhaukus

careful, the subtraction is the upper line - the lower line |dw:1441765283898:dw|

14. UnkleRhaukus

right?

15. anonymous

ok, but how is it -5y?

16. UnkleRhaukus

-4y - (+y) = -4y -y = -5y

17. UnkleRhaukus

(y^2-4y-5) - (y^2+y) = -5y -5

18. anonymous

Ok, lol I keep looking at the - like a minus not a negative. What's the next step?

19. UnkleRhaukus

only one more round to go, but there is no more room

20. anonymous

What do you mean?
