in general, this type of problem require that we complete the square.
\n" ); document.write( "Remember,,separate the x^2 and x^1 terms,,,x^2 must have coefficient =1,,take 1/2 od x^1 coefficient,,,and square it for third term.,,,then add compensating term to equation to balance.
\n" ); document.write( ".
\n" ); document.write( "x^2 -4x -4y^2 -24y =48
\n" ); document.write( ".
\n" ); document.write( "{x^2 -4x }-4{y^2 +6y } =48
\n" ); document.write( ".
\n" ); document.write( "{x^2 -4x -4} -4 {y^2 +6y +9} = 48 -4 -36 = 8,,,,,,(-4*9 = -36)
\n" ); document.write( ".
\n" ); document.write( "{ x-2}^2 -4 {y+3}^2 =8
\n" ); document.write( ".
\n" ); document.write( "divide thru by 8
\n" ); document.write( ".
\n" ); document.write( "{(x-2)^2}/8 -{ (y+3)^2}/2 =1
\n" ); document.write( ".
\n" ); document.write( "This is the std form of a hyperbola
\n" ); document.write( ".
\n" ); document.write( "(x-h)^2 /a^2 - (y-k)^2/b^2 =1\r
