Can you solve it by using matrix notation?

Question 03 Consider the regression of y on X1 and X2: y = Xi Bi + X2 B2 + u nx1 nxk kx1 nxky kox1 (1) nxi Also consider another regression of y on X2: y = X2 82 + v nx1 nxky ky x1 nxi (2) Does the SSR of model (1) equal to SSR of model (2)? If not, what condition(s) must be satisfied to equalize
