SUMMARY
The discussion focuses on determining if the vectors a = (2, -3, 2), b = (1, 1, -1), and c = (8, 5, -2) can form a basis for R^3. Participants suggest using the dot product and scalar triple product to assess linear independence. The conclusion is that since the dot product of the cross product of vectors a and b with vector c yields a non-zero result (18), the vectors cannot serve as a basis for R^3. A reminder is provided that three linearly independent vectors are required to form a basis.
