[(1/x+4)-1/4]/x

Lim -> 0

Substitution, factoring and conjugate multiplication don't work

The question tells me to multipy the top and bottam by the lcd of the little fractions namely 4(x+4)

--here I am a little confused, did all the book do is take both denominators (x+4) and 4 and make them the LCD together?

So like if my question was for example like this,

[(1/2x+3)-1/4]/x

My LCD would be 4(2x+3), am i wrong?

Thanks
