    Quadratic Equation

    (a) (t - u)^2 + 2u(t - u) = t^2 - u^2

    After converting the original quadratic equation (ax^2 + bx + c = 0) into
    x^2 + (b/a)x = -(c/a)
    introduce the auxilliary variables t and u, where x = t - u. Then, using (a), find t and u (and ultimately x) in terms of a, b, and c.

    Is that all of it?

    Is there some context to go with this which might explain what you are asking for?

    That is it. It feels good to know that I'm not the only one confused.
