Solve the following equation for x | x a x b | | b x a x | = 0 | x b x a | | a x b x | (Determinant equals zero). I'm not sure how to do this and any help would be appreciated!

I'm not sure how to do this and any help would be appreciated! Do you know how to evaluate a 4x4 determinant? Can you evaluate each of these 3 x 3 determinants?
Before I continue with the rather length process, isn't there still the problem of 3 variables with only 1 equation?
Your answer will be in terms of a and b. You can reduce the work with some row operations.
