Question 439447
Given that A = [2  3]
               [1  0]

and B = [1  4]
        [0  1],

evaluate {{{(A)^2 - AB}}}
-----------------------------------
A^2 = [2*2+3*1...2*3+3*0]
......{1*2+0*1...1*3+0*0]

= [7...6]
..[2...3]
-------------------------------------
AB = [2+0...8+3]
.....[1+0...3+0]

= [2...11]
..[1....3]

====================
A^2+AB = [9...17]
.........[3....6]
