WebIf the matrix has more rows than columns, a row of all zeros does not imply a free variable. For example: $$ \left[\matrix{1 & 2\cr 3 & 4\cr 0 & 0\cr}\right]$$ One way you find free variables is: put the matrix into row-echelon form, then any column that does not contain the first nonzero entry of any row corresponds to a free variable. In your ... Webif 0 = A 2 + 2 A + I = ( A + I) ( A − I) you have that the set { + 1, − 1 } contains all the eigenvalues of A. thus 0 is not an eigenvalue of A and this is equivalent to being invertible. Edit: as LutzL has commented correctly, A − I has to be replaced by A + I and thus { − 1, + 1 } by { − 1 }. The arguments still work. Share Cite radio jmfm
