@.Sam.

OpenStudy (anonymous):

for you make 3m-9=0 3m=9 m=9/3 m=3 so for m=3 this fraction is undefined

OpenStudy (anonymous):

R u sure thats right lol. I suck at math so idk

OpenStudy (anonymous):

yeah it is lol

OpenStudy (anonymous):

k can u do another one lol

OpenStudy (anonymous):

sure

OpenStudy (anonymous):

x^2+6x+9/5x+15 (solve?)

hero (hero):

If this is simplification, then \[\frac{m-3}{3m - 9} = \frac{m - 3}{3(m - 3)} = \frac{1}{3} \dot\ \frac{m-3}{m-3}\] Cancel where necessary to simplify

OpenStudy (anonymous):

I need this one^^^^^ the second one not the first one lol

hero (hero):

You need the first one too. You need to learn how to do all of them.

hero (hero):

Hint: \[\frac{(x + 3)(x + 3)}{5(x + 3)} = \frac{(x+3)}{5} \dot\ \frac{x+3}{x+3}\] Cancel and simplify where needed
