Perform the indicated operations and simplify the following expression:
\n" ); document.write( "[(x+6)/(x^2-16)] * [(3x-12)/(3x+18)]
\n" ); document.write( "Factor where you can to get:
\n" ); document.write( "[(x+6)/[(x-4)(x+4)]] * [3(x-4)/[3(x+6)]
\n" ); document.write( "Cancel any fact that is common to numerator and a denominator
\n" ); document.write( "such as (x+6) and (x-4) and 3
\n" ); document.write( "-------
\n" ); document.write( "= [1/[(x+4)]] * [1/[1])]\r
\n" ); document.write( "\n" ); document.write( "= 1/(x+4)
\n" ); document.write( "============
