Question 864317
{{{(x^2-4)/(x^2-4x+4)}}}



{{{((x-2)(x+4))/((x-2)(x-2))}}}



{{{(highlight((x-2))(x+4))/(highlight((x-2))(x-2))}}}



{{{(cross((x-2))(x+4))/(cross((x-2))(x-2))}}}



{{{(x+4)/(x-2)}}}



=======================================================



So {{{(x^2-4)/(x^2-4x+4)}}} simplifies to {{{(x+4)/(x-2)}}}
