Inverse of 2×2 Matrix Formula Let A = [ a b c d] be the 2 x 2 matrix. The inverse of matrix A can be found using the formula given below. A − 1 = 1 a d − b c [ d − b − c a] Here, ad – bc = det (A) {determinant of the matrix A} And [ d − b − c a] is the adjoint of matrix A.

If a 2×2 matrix A is invertible and is multiplied by its inverse (denoted by the symbol A−1 ), the resulting product is the Identity matrix which is denoted by I I. To illustrate this concept, see the diagram below. In fact, I can switch the order or direction of multiplication between matrices A and A −1, and I would still get the Identity matrix

Note that the result of multiplying the two matrices together is the identity matrix. Pairs of square matrices which have this property are called inverse ...

Inverse of 2x2 Matrix. Before going to see how to find the inverse of a 2x2 matrix, let us recall the meaning of inverse. In general, the inverse of a real number is a number which when multiplied by the given number results in the multiplicative identity, which is 1.
