This article on Inverse of a 2 × 2 Matrix helps you find the answer to the question asked in many exams, i.e., "What is the Inverse of any 2x2 Matrix?". Also, we will learn what is inverse, how to calculate it for a 2x2 matrix, and some solved examples of the same.
The inverse of a matrix A is A – 1, such that multiplying the matrix with its inverse results in the identity matrix, I. In this lesson, we will take a brief look at what an inverse matrix is, find the inverse of a 2 × 2 matrix, and the formula for the inverse of a 2 × 2 matrix. There will be a lot of examples for you to look at.

The inverse of a 2×2 2 × 2 matrix can be found using the formula 1 ad− bc [d −b −c a] 1 a d - b c [d - b - c a] where ad−bc a d - b c is the determinant.
How to find the Inverse of a 2×2 Matrix? The following diagram gives the formula used to find the inverse of a 2x2 matrix. Steps to Find the Inverse: Calculate the determinant (ad - bc). Swap a and d, and change the signs of b and c. Multiply the modified matrix by 1 divided by the determinant. Simplify the fractions (if possible).
So, to find the inverse of a 2 × 2 matrix: Step1: Calculate the determinant (a d − b c). Step2: If the determinant is not zero, swap the positions of a and d. Step3: Change the signs of b and c. Step4: Divide each term in the matrix by the determinant. The resulting matrix is the inverse of the original matrix.
