anonymous 5 years ago Hi do anyone know how to do Rational Expressions. m+6/m^2-3m+2m-1/m^2+5m-14

1. anonymous

is it :$\frac{m+6}{m^2-3m} + \frac{2m-1}{m^2+5m-14}?$

2. anonymous

m+6m2−3m+2 +2m−1m2+5m−14 there's two (2)s but that setup is right

3. anonymous

no fractions? lol I'm confused now

4. anonymous

lol yes fractions i just dont know how to put it on. its my first time on this. your set up is right. but you were missing a number 2 on m^2-3m+2 =)

5. anonymous

try to put brackets for those with fractions :)

6. anonymous

oh, so my equation was right? all I have to do is add a 2?

7. anonymous

yes

8. anonymous

okay :)

9. anonymous

=) your soo awesome for helping me double =D

10. anonymous

lol ^_^

11. anonymous

thank you )

12. anonymous

lol

13. anonymous

alright, so after factoring the denominators we'll get:$\frac{m+6}{(m-1)(m-2)} + \frac{2m-1}{(m+2)(m-7)}$ now get them to have the same denominators: $\frac{(m+6)(m+2)(m-7) + (2m-1)(m-1)(m-2)}{(m+2)(m-2)(m-1)(m-7)}$

14. anonymous

hmmm, there's something wrong

15. anonymous

are you sure of your question?

16. anonymous

LOL! WAIT!

17. anonymous

I got the mistake >_< sorry!

18. anonymous

it's supposed to be : $\frac{(m+6)(m+7) + (2m-1)(m-1)}{(m-2)(m-1)(m+7)}$

19. anonymous

so :

20. anonymous

$= \frac{m^2+13m+42+2m^2-3m+1}{(m-1)(m-2)(m+7)}$$= \frac{3m^2+10m+43}{(m-1)(m-2)(m+7)}$

21. anonymous

hmm, I'm not sure if we can simplify any further, correct me if I;m wrong please :)

22. anonymous

23. anonymous

lol, yeah I got the question, but I'm not sure of my answer :)

24. anonymous

I am sure of my steps though :)

25. anonymous

26. anonymous

thank youuu soooo much!!!

27. anonymous

all I did was factor and get them to have the same denominator, and you're welcome ^_^

28. anonymous

=) but why did you do those steps

29. anonymous

or how? so i can do them for more problems
