## jmyers484 2 years ago factor m from the expression: 5mn=3m

1. VincentDonkoh

m=0 is that correct?

2. jmyers484

well i got m = 0 and n =-8 im not sure what i should put down as my aswer lol

3. jmyers484

so if u got m=0 n i did too then i guess thats the answer

4. VincentDonkoh

I think u will have to use the m=0, because u were asked to factor out m from the expression

5. jmyers484

ive been awake for to long lol

6. VincentDonkoh

Oh then you will be very tired then. but what were you doing all along?

7. UnkleRhaukus

$5mn=3m$$\quad5n=3$

8. VincentDonkoh

How? why did you cancel out the m's ?

9. UnkleRhaukus

they were common

10. VincentDonkoh

but don't you think in this case you are suppose to make m the subject?

11. UnkleRhaukus

the question asks us to factor m from the expression I factored m right out of the expression

12. VincentDonkoh

ok, think av got ur idea!

13. jmyers484

unkle u rock bro

14. jmyers484

worked night shift, got class in a couple hours and im cathcing up on homework

15. VincentDonkoh

Uncle, take a luk at the question again, u wer asked to 'factor m from' the expresion, so m must not be missin from it but rather ,it must stand out in the expression

16. jmyers484

so is it m = 0 or n=-8m?

17. VincentDonkoh

In that case , 5mn=3m => 5mn-3m=0 m(5n-3)=0 m=0/(5n-3) m=0

18. jmyers484

you guys seem to be having fun with this one

19. VincentDonkoh

sure! u'v got help us out.

20. jmyers484

haha well factoring the m out is still factoring it and whateve process we use we end up with m=0

21. jmyers484

well first i came to n=-8m and that is simplified to 0 anyway

22. jmyers484

so i like the process unkle used cause its simple that way
