Question 1024834

This is a nesting fraction.  I tried the question on two different sites
when my main site, which has taught me a lot, didn't make sense.  The question is or problem is 2+2/x (numerator) 4-4/x (denominator)  What is the correct answer please. (Its suppose to be reduced as much as possible for the answer.)
<pre>Correct answer: {{{2(x + 1)/4(x - 1)}}} = {{{cross(2)(x + 1)/2cross(4)(x - 1)}}} = {{{highlight_green(matrix(1,3, (x + 1)/(2(x - 1)), or, (x + 1)/(2x - 2)))}}}
