I wonder if some one would kindly shed some light on some of my following queries   1. In the third term why is it a -4 ?  2.  Also in the third term why x-1 instead of -x+1 for one of the numerators ? 3. In the second term  3x/1-x if a greater explanation of how the denominators are ahieved ? especially 1-x (-(x+1)(-x+1) and finally 4. Factoring the total numerator if perhaps a break down explanation is given. as this all would be most appreciated for furthering my studies kind regards. </SPAN>\n" );
