$\"9y-%28-4y-2x%29\"$
\n" ); document.write( "The tricky part here is to recognize the implications of that minus sign in front of the parenthesis. Think of it as a -1 multiplying everything inside the parenthesis, like this:
\n" ); document.write( " $\"9y%2B%28-1%29%28-4y-2x%29\"$
\n" ); document.write( "Now, when you \"remove\" the parenthesis, you can see that you are really multiplying through by -1:
\n" ); document.write( " $\"9y%2B4y%2B2x\"$
\n" ); document.write( "Now, you can combine \"like\" terms for the final answer:
\n" ); document.write( " $\"highlight%2813y%2B2x%29\"$
