stores range of bivariate quadratic term in resultant
Given scalars \f$a_x\f$, \f$a_y\f$, \f$a_{xy}\f$, \f$b_x\f$, and \f$b_y\f$ and intervals for \f$x\f$ and \f$y\f$, computes interval for \f$ a_x x^2 + a_y y^2 + a_{xy} x y + b_x x + b_y y \f$.
\attention The operations are not applied rounding-safe here!
