Is the LCD of this equation
-5/(3x-9)+4/(x-3)=5/6
18(x-3) or 6(x-3)

Question

Is the LCD of this equation
-5/(3x-9)+4/(x-3)=5/6
18(x-3) or 6(x-3)

anonymous · Answer

This should clear it up a little bit
$$\frac{-5}{(3x-9)}+\frac{4}{(x-3)}=\frac{5}{6}$$

anonymous · Answer

3*x-9

anonymous · Answer

Am still lost because when 3x-9 is factored it is 3(x-3)... and you have to factor the 6 in 5/6 to 3*2 and when you find the common factor in them shouldn't it be 3*2(x-3)...?

anonymous · Answer

well for the lhs it is 3x-9

anonymous · Answer

Umm, how did you get that timo?

anonymous · Answer

but if you set equation = to 0
-5/(3*x-9)+4/(x-3)-5/6=0
lhs common denom is  


6*x-18

anonymous · Answer

Oh, okay I see where your coming from... Idk which one to go with... but thanks so much!!!

anonymous · Answer

LOL ask around also cuzz I am not exactly sure :P

anonymous · Answer

okay... thanks

anonymous · Answer

it also simplifies to this

7/(3*(x-3)) = 5/6
