You can put this solution on YOUR website!
I'm assuming that you want to factor.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"8r%5E3-64r%5E2%2Br-8\" Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%288r%5E3-64r%5E2%29%2B%28r-8%29\" Group like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"8r%5E2%28r-8%29%2B1%28r-8%29\" Factor out the GCF \"8r%5E2\" out of the first group. Factor out the GCF \"1\" out of the second group\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%288r%5E2%2B1%29%28r-8%29\" Since we have the common term \"r-8\", we can combine like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"8r%5E3-64r%5E2%2Br-8\" factors to \"%288r%5E2%2B1%29%28r-8%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"8r%5E3-64r%5E2%2Br-8=%288r%5E2%2B1%29%28r-8%29\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
