Someone wanna help a girl out? (x/5)-(5/x)=0
hahahhah..lol @what you said before the ques!! :D
Well no one will help me!!):
coercion, lol what is the least common multiple of the two denominators?
x? 5? i don't know..
when you have two different denominators like that you can always multiply them together to get a common denominator (though if you just multiply them all it may not be the *least* common multiple) so in your case your common deonominator is \(5\times x=5x\)
Okay then what?
now multiply the whole equation by that
then please show what you have left after I will help you from there
I have 5x(x/5-5/x=0).. How do you multiply that?
well first you can distribute on the left (I am only writing the left side right now):\[5x(\frac x5+\frac5x)=5x\cdot\frac x5+5x\cdot\frac5x\]can you simplify this?
Dude.. You just confused me.
do you know how to distribute?\[a(b+c)=ab+ac\]^look familiar?
uh uh..
how about hit and trial an x=5 and -5..case closed! ;)
so that is what we did above a=5x b=x/5 c=5/x then we just distributed like usual
\[5x(\frac x5+\frac5x)=5x(\frac x5)+5x(\frac5x)\]now simplify what is\[5x(\frac x5)\]?
