I am very much in need of your help. I have a question saying:

Let x,y E R. Show that det(I-xy'T)= 1-y'T x

y'T is transpose of y and I is identity matrix.

Actually I dont know how to solve something like det( A-B). What am I going to do when there is addition or subtraction in the determinant.

Thanks for your response.
