Complete the square,
\n" ); document.write( " $\"y=x%5E2-x-23\"$
\n" ); document.write( " $\"y=%28x%5E2-x%2B1%2F4%29-23-1%2F4\"$
\n" ); document.write( " $\"y=%28x-1%2F2%29%5E2-92%2F4-1%2F4\"$
\n" ); document.write( " $\"y=%28x-1%2F2%29%5E2-93%2F4\"$
\n" ); document.write( "The vertex is (1/2,-93/4).
\n" ); document.write( " $\"0=%28x-1%2F2%29%5E2-93%2F4\"$
\n" ); document.write( " $\"%28x-1%2F2%29%5E2=93%2F4\"$
\n" ); document.write( " $\"x-1%2F2=0+%2B-+sqrt%2893%29%2F2\"$
\n" ); document.write( " $\"x=1%2F2+%2B-+sqrt%2893%29%2F2\"$
