\n" ); document.write( "Write the standard equation of this conic section:
\n" ); document.write( "y^2-x^2+2y-14x-57
\n" ); document.write( "(y^2+2y+1)-1 -(x^2+14x+49)+ 49 - 57 = 0
\n" ); document.write( "(y+1)^2 - (x+7)^2 = 9
\n" ); document.write( "Standard Form:
\n" ); document.write( "\"%28y%2B1%29%5E2+%2F9+-+%28x%2B7%29%5E2%2F9+=+1\"
