\n" ); document.write( "You have not shown the expression correctly, so none of the given answer choices is correct.

\n" ); document.write( "g-3/f-1 --> \"g-3%2Ff-1\"

\n" ); document.write( "Substitute 3/g for f:

\n" ); document.write( "\"g-3%2F%283%2Fg%29-1\"
\n" ); document.write( "\"g-3%28g%2F3%29-1\"
\n" ); document.write( "\"g-g-1\"
\n" ); document.write( "\"-1\"

\n" ); document.write( "ANSWER: -1

\n" ); document.write( "You can get yourself into all kinds of trouble if you are sloppy with your use of parentheses.

\n" ); document.write( "From the given answer choices, it is clear that the expression to be simplified is in fact

\n" ); document.write( "(g-3)/(f-1) --> \"%28g-3%29%2F%28f-1%29\"

\n" ); document.write( "Let's do that....

\n" ); document.write( "Substitute 3/g for f and simplify:

\n" ); document.write( "\"%28g-3%29%2F%283%2Fg-1%29\"
\n" ); document.write( "\"%28g-3%29%2F%28%283-g%29%2Fg%29\"
\n" ); document.write( "\"%28g-3%29%2A%28g%2F%283-g%29%29\"
\n" ); document.write( "\"-g\"

\n" ); document.write( "ANSWER: -g (answer choice 5)

\n" ); document.write( "
\n" ); document.write( "
\n" );
