    You need to know how to calculate a determinant. I suggest you review your class notes or textbook and then if you need more help, please be specific about what your difficulty is.

    Well, you can't- that's obviously not true. The determinant on the left will involve x^2 while the determinant on the right does not. You could reduce this to a quadrartic equation and solve for values of x that make it true.

    What do you get for the two determinants?
