You can put this solution on YOUR website!
Hint: Recall that

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

\n" ); document.write( "\n" ); document.write( "So this means that

. \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So plug in

to get

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

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

and plug that in to get:

. \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "At this point, we have a quadratic which can be solved by the quadratic formula. You'll get solutions in terms of 'z', so you'll need to remember to use

to find the solutions in terms of 'x'. Let me know if you still need help. \n" ); document.write( "
