Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

Group like terms (i.e. pair the real components with each other and pair the imaginary components with each other)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

Combine like terms. So it is now in $\"a%2Bbi\"$ form where $\"a=4\"$ and $\"b=3\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
