Question 83415
{{{6/r - 5/(r-2 ) }}}


The LCD in this problem is {{{r(r-2) }}}

Next, you must convert each of the fractions into fractions with denominators r(r-2).  You do this by multiplying numerator and denominator of the first fraction by (r-2), and the second fraction by r.


{{{6/r - 5/(r-2 ) }}}
{{{(6/r)*((r-2)/(r-2)) - (5/(r-2 ))*(r/r)  }}}

{{{ (6r-12 - 5r) /(r(r-2)) }}}


{{{ (r-12)/(r(r-2)) }}}
