Page no. So A Characteristic polumonial LA-AL=0 of A is given by expanding along Re, we have (3-a) [Q-2)(3-0) -2] +2 [-1(3-0)and Hence one eigen value of A=0 other eigen values are 494 Te = 0,4,4 – eigen values. first let eggen value d=0 Put a=0 in JPage no. --2-24-2 =0) -2-24-2=0 or n+24+2=0 -2-2-2 od Me system has only one free variable. This a -non-zero solation ay na,
