Problem 1.29 #3

------------------------

Hello guys, i've been given a problem like the one above in my assignments and i'm not really sure what the final answer is supposed to be like. So far here is what i've done: just multiplied each 2x2 matrix by a scalar and added them up... this question is worth 20 marks and i get a sense that it is incomplete, what am i missing here?

Does this look right? i've never come across anything like that in my books and it's worth 20 marks so i have to be careful. any input you give will be appretiated
