Question 116863
how do you solve this rational expression.... for allr is not equal to 2
{{{(r^2-5r+6)/(r^2-4)}}}
:
Note that you can factor the numerator and the denominator is the difference of squares, you can factor also, then cancel out (r-2)
{{{((r-3)(r-2))/((r+2)(r-2))}}} = {{{(r-3)/(r+2)}}}
