Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.From cayley hamilton theorem trace=5+b=4 matlab b=-1
Uske baad determinant is -21 so a can be found accordingly ig?
-10-6+a=-21
toh a=-5
Which means the answer would be -13
yeh trace wala point kahan se aa gya
i dont remember doing this
Are you familiar with characteristic equation of a matrix?
ive done cayley hamilton yes
|A-lambda I | = 0
Jo iske sum of roots hai wo trace hai, jo iske product of roots hai wo determinant
Aisa property hai iska
Is this resolved?
yeahh
