[SOLVED] Help please?
hello i think im posting in wrong forum for that im sorry but recently i started my A level's and one of my choices was further maths. lately i havent been able to grasp a few things in class. for example
given that "m" is a 2x2 matix
Show that "m squared" = m + I
Show that "m^4" - 3m = 2I
wondering if anyone could help i just can't grasp on how to do this atm..all help will be very much appreciated thankyou.
sorry to have bothered you guys...i feel like such an idiot now how simple it actually is to work this out you can remove this post sorry again and thanks.
