Question 910631
reduce the rational expression to its lowest term: <s>x subtract x squared divided by x squared plus x subtract 2?</s>

x-x^2/x^2+x-2=??


No.  Not that.


THIS:
(x-x^2)/(x^2+x-2)


Which becomes this when the rendering tagging is used:
{{{(x-x^2)/(x^2+x-2)}}}


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


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


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