When the form is $\"y+=+ax%5E2+%2B+bx+%2B+c\"$ the axis
\n" ); document.write( "of symmetry is $\"x+=+%28-b%29+%2F+%282a%29\"$
\n" ); document.write( " $\"%28-b%29+%2F+%282a%29+=+%28-%28-9%29%29+%2F+%282%2A1%29\"$
\n" ); document.write( " $\"%28-b%29+%2F+%282a%29+=+9%2F2\"$
\n" ); document.write( " $\"x+=+9%2F2\"$ is the axis of symmetry \n" ); document.write( "

\n" );
