Consider the following matrices.

A = < 2="" 2="" 1="" 2="" 2="" 1=""> , B = < 1="" 2="" 2="" 1="" 3="" 1=""> , C = <1 2="" 3="" 4="">

Evaluate each of the following expressions, if the result exists. If it does not exist, state a reason why. Show all work. You must solve these equations by hand, without the aid of any calculator or tool.

(a)  CA

(b)  2BC + BA

(c)  2AT C + BC
