If a and adbc then a is not invertible
Witrynaad+bc = 0. bd(ω+1) = 0 If bd = 0, then ad+bc = 0 implies either a or b must be 0. But since u = 1, neither a nor b can be 0. Therefore, we must have ω+1 = 0, i.e. ω = -1. … WitrynaTranscribed Image Text: If A = a b c d then A is invertible if ad- bc = 0, in which case A-1 = 1 -b ² bed b a ad - bc If ad bc = 0, then A is not invertible.
