    the general form of a quadratic equation is: \[a{x^2} + bxy + c{y^2} + dx + ey + f = 0\]

    if we consider a quadratic equation in one variable: \[a{x^2} + bx + c = 0\] then we can rewrite your equation as follows: \[\frac{3}{4}{x^2} - 2 = 0\]

    or: \[3{x^2} - 8 = 0\]

    no, since we have rewritten your equation using integers parameters

    so, I think that a possible choice, can be this: a=3, b=0, c=-8
