Question 914675
{{{ ((x^2-25)/(2x-2))/((x^2+10x+25)/ (x^2+4x-5)) }}}



{{{ ((x^2-5^2)/2(x-1))/((x+5)^2/ (x^2-x+5x-5)) }}} 



{{{ (((x-5)(x+5))/2(x-1))/(((x+5)(x+5))/ ((x^2-x)+(5x-5))) }}}



{{{ (((x-5)(x+5))/2(x-1))/(((x+5)(x+5))/ (x(x-1)+5(x-1))) }}}



{{{ (((x-5)(x+5))/2(x-1))/(((x+5)(x+5))/ ((x+5)(x-1))) }}}



{{{ (((x-5)cross((x+5)))/2cross((x-1)))/((cross((x+5))cross((x+5)))/ ( cross( (x+5)) cross((x-1)) ) ) }}}



{{{ (x-5)/2}}}
