\n" ); document.write( " $\"%28r%2Bg%29%28r%5E2-r%2Ag%2Bg%5E2%29\"$ Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"r%28r%5E2-r%2Ag%2Bg%5E2%29%2Bg%28r%5E2-r%2Ag%2Bg%5E2%29\"$ Expand.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

Distribute.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"r%5E3-g%2Ar%5E2%2Bg%5E2%2Ar%2Bg%2Ar%5E2-g%5E2%2Ar%2Bg%5E3\"$ Multiply.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"r%5E3%2Bg%5E3\"$ Now combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " So $\"%28r%2Bg%29%28r%5E2-r%2Ag%2Bg%5E2%29\"$ expands to $\"r%5E3%2Bg%5E3\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, $\"%28r%2Bg%29%28r%5E2-r%2Ag%2Bg%5E2%29=r%5E3%2Bg%5E3\"$ .\r
