Hi,
Ok so i have this question i have have some problem solving (I've done A)
We have two nxn matrixes A and B and it says that A=I-AB
question part A:
prove that A is regular and AB=BA (done this one prety easy)
question part B:
prove that if B is simetrical, so is A
question part C:
Prove that B^3=0 if and only if A=I-B+B^2
Thanks in advance
