WebEDIT (8/14/2024): A couple people have suggested that this answer should come with a warning -- this is a pretty fancy approach to an elementary question, motivated by the fact that I know the OP's interests. Some of the other answers below are probably better if you just want to invert some matrices :). I've also fixed a couple of minor typos. WebFor a 2x2 matrix, the inverse is: ( a b c d) − 1 = 1 a d − b c ( d − b − c a) , where a d − b c ≠ 0. just swap the 'a' and 'd', negate the 'b' and 'c', then divide all by the determinant a d − …
