I have to express the following rational expressions in lowest terms Can you please help with the following questions. I am so confused and I don't quiet understand. There are five questions that I tried and can't get. PLEASE HELP ME!!!!
\n" ); document.write( "1) \"x%2F%28%28x%2Bxy%29%29\"
\n" ); document.write( "Factor x out in the denominator, then cancel with the x in the numerator:
\n" ); document.write( "\"x%2F%28x%281%2By%29%29\" = \"1%2F%28%28y%2B1%29%29\"

\n" ); document.write( "Factor out 3x in both the numerator and denominator; cancel the 3x's
\n" ); document.write( "\"%283x%28x%2B2%29%29%2F%283x%28x%2B3%29%29\" = \"%28x%2B2%29%2F%28x%2B3%29\"

\n" ); document.write( "You can factor the numerator here; cancel one of the (x+1)'s leaving:
\n" ); document.write( "\"%28%28x%2B1%29%28x%2B1%29%29%2F%28%28x%2B1%29%29\" = x+1

\n" ); document.write( "\"%282%28x-3%29%28x%2B1%29%29%2F%28%28x-3%29%29\" = 2(x+1)
