If `A=[(1, 0),(-1 ,7)]` , find `k` such that `A^2-8A+k I=O` .

If A=[{:(1,0),(-1,7):}] , thenfind k such that A^(2)-8A+kI=O .

If A=[[1,0-1,7]], find k such that A^(2)-8A+kI=O

If A = [(1, 0),(-1,7)] find K so that A^2 = 8A + KI .

If A={:[(1,0),(-1,7)] and I={:[(1,0),(0,1)] , then find k so that A^(2)=8A+kI

If A=[[1,0],[-1,7]] find k so that A^2-8A-kI=O ,where I is a unit matrix and O is a null matrix of oreder 2.
