If then find (-A2 + 6A).

Given :


Matrix A is of order 2 2.


To find : -A2 + 6A


Formula used :



Where cij = ai1b1j + ai2b2j + ai3b3j + ……………… + ainbnj


If A is a matrix of order a b and B is a matrix of order c d ,then matrix AB exists and is of order a d ,if and only if b = c


A2 = = =


A2 =


-A2 = =


6A = 6 × =


6A =


-A2 + 6A = + = =


-A2 + 6A =
