$\"%28%284x%5E2-20x%2B3%29%2F%282x%2B1%29%29%2B%28%282x%5E2-25x-27%29%2F%284x%2B2%29%29\"$
\n" ); document.write( "The denominators have a common factor of $\"%282x%2B1%29\"$ :
\n" ); document.write( " $\"%28%284x%5E2-20x%2B3%29%2F%28%282x%2B1%29%29%29%2B%28%282x%5E2-25x-27%29%2F2%282x%2B1%29%29\"$ so if you multiply the first fraction by $\"2%2F2\"$ you will then have a common denominatot of $\"%284x%2B2%29\"$ and this is the LCD.
\n" ); document.write( " $\"%282%284x%5E2-20x%2B3%29%2F2%282x%2B1%29%29%2B%28%282x%5E2-25x-27%29%2F2%282x%2B1%29%29\"$ or...

\n" ); document.write( "Now you can add the two fractions.
