The standard form is $\"%28x+-h%29%5E2+=+4p%28y+-k%29\"$ , where \r
\n" ); document.write( "\n" ); document.write( "the focus is (h,k + p) \r
\n" ); document.write( "\n" ); document.write( " $\"%28x-1%29%5E2-2%28y%2B1%29=0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28x-1%29%5E2=2%28y%2B1%29\"$ .......... $\"4p=2\"$ .....-> $\"+p=1%2F2\"$ \r
\n" ); document.write( "\n" ); document.write( "so,...->...the focus is (1, -1 + 1/2)............the focus is (1, -1/2)\r
\n" ); document.write( "\n" ); document.write( "and \r
\n" ); document.write( "\n" ); document.write( "the directrix is y = -1 - 1/2=-3/2.\r
