I'm assuming you mean $\"f%28x%29=-2x%5E2-12x-16\"$
\n" ); document.write( "Convert to vertex form by completing the square.
\n" ); document.write( " $\"f%28x%29=-2%28x%5E2%2B6x%29-16\"$
\n" ); document.write( " $\"f%28x%29=-2%28x%5E2%2B6x%2B9%29-16%2B18\"$
\n" ); document.write( " $\"f%28x%29=-2%28x%2B3%29%5E2%2B2\"$
\n" ); document.write( "(-3,2) is the vertex.
\n" ); document.write( " \n" ); document.write( "
