    Linear transformations question

    Hi this is my first post to this forum and hopefully will not be my last. I'm having difficulty with this question and require help.

    Using suitable transformations write the function
    3x^2+8x-2xy-5y-y^2+19=0 in the form
    AX^2+BY^2=1
    I believe A & B are constants. Anyone have an idea how to approach this ?

    There are several ways to do this, but I'm guessing that this is a question about rotation of axes. Go to that link for further information!
