\n" ); document.write( "the LCM of two polynomials is their product divided by their greatest common divisor. \r
\n" ); document.write( "\n" ); document.write( "\"x%5E2-4x=x%28x-4%29\", \r
\n" ); document.write( "\n" ); document.write( "\"x%5E2%2B4x=x%28x%2B4%29\"\r
\n" ); document.write( "\n" ); document.write( "Here the greatest common divisor is \"x\", so the LCM is \"x%28x-4%29%28x%2B4%29\"
