    This is the Equation \[x ^{2} + 3*x*y -5*x -4*y -5 =0\]

    hyperbola equation== \[x^{2} \div a ^{2} - y^{2} \div b ^{2} =1\]

    for translation x = X - h y = Y - k

    For rotation \[ x = X \cos \theta - Y \sin \theta \\ y = Y \cos \theta + X \sin \theta \]

    do you want to reduce it to standard form?? \[ \frac {x^2}a - \frac {y^2} b = 1 \] ??

    It's indeed a hyperbola i guess translation first http://www.wolframalpha.com/input/?i=plot+2+*+x+^+2+%2B6+*+x+*+y+%2B2+*+y+%3D+10+*+%28x+%2B+y+%2B1%29 then rotation

    I guess rotation first ... to eliminate the homogeneous form xy http://staff.argyll.epsb.ca/jreed/math30p/conics/standard.htm
