You can put this solution on YOUR website!
The x value will be the same as that of the vertex. Put the equation into standard form through Completion of the Square. You can start with the step,
\n" ); document.write( " $\"y=-3%28x%5E2%2B2x%29%2B4\"$
\n" ); document.write( " $\"y=-3%28x%5E2%2B2x%2B1%29%2B4-%28-3%29%2A1\"$
\n" ); document.write( "... and YOU should finish this. \r
