Let \(\vec \alpha = \left( {\lambda - 2} \right){\rm{\vec a}} + {\rm{\vec b\;and\;}}\vec \beta = \left( {4\lambda - 2} \right)\vec a + 3\vec b\) be two given vectors where vectors \({\rm{\vec a\;and\;\vec b}}\) are non-collinear. The value of λ for which vectors \(\vec \alpha {\rm{\;and\;}}\vec \beta \) are collinear is:
