$4x^2+12x-16/2x+10 divided be 6x+24/x^2+9x+20$

flip the 2nd fraction to its reciprocal and change to multiplication, then factor and terms should cancel|dw:1436217406459:dw|

7. anonymous

OUCH! Ok:) gHold on

8. anonymous

4(x-1)(x+4)/2(x+5)

9. anonymous

(x+5)(x+4)/6(x+54) is the 2nd one

10. anonymous

how'd you get 6(x+54) for the 2nd denominator?

11. anonymous

i mean 6(x+4)

12. anonymous

ok yeah. so then you just cancel anything that's in both the numerator and denominator

13. anonymous

so i got x-1/3(X+4) s as my answer

14. anonymous

I got $\frac{ (x-1)(x+4) }{ 3 }$

15. anonymous

oh ok

16. anonymous

So maybe I did something wrong?

17. anonymous

it looks like you canceled both the (x+4) from the numerator instead of one from each the numerator and denominator

18. anonymous

compare yours to the work in the link

19. anonymous

ohh p I see! So yeah , I get what I did wrong. Thanks:)

20. anonymous
