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

1. anonymous

m=0 is that correct?

2. anonymous

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

3. anonymous

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

4. anonymous

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

5. anonymous

ive been awake for to long lol

6. anonymous

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

7. UnkleRhaukus

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

8. anonymous

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

9. UnkleRhaukus

they were common

10. anonymous

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. anonymous

ok, think av got ur idea!

13. anonymous

unkle u rock bro

14. anonymous

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

15. anonymous

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. anonymous

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

17. anonymous

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

18. anonymous

you guys seem to be having fun with this one

19. anonymous

sure! u'v got help us out.

20. anonymous

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

21. anonymous

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

22. anonymous

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