If $\overline{\mathrm{a}}, \overline{\mathrm{b}}, \overline{\mathrm{c}}$ are non - coplanar vectors and $\mathrm{\lambda }$ is a real number then

$\left[\mathrm{\lambda }\right(\overline{\mathrm{a}}+\overline{\mathrm{b}}) {\mathrm{\lambda }}^2\overline{\mathrm{b}} \mathrm{\lambda }\overline{\mathrm{c}}] = [\overline{\mathrm{a}} \overline{\mathrm{b}}+\overline{\mathrm{c}} \overline{\mathrm{b}}]$ for
