NettetMatrix A is not invertible. Correct answer: Explanation: For any 2x2 matrix, to determine if it is invertible, we must first calculate its determinant. If the determinant is equal to 0, then the matrix is not invertible. If it isn’t equal to 0, then its inverse can be found using this formula: Report an Error Example Question #6 : The Inverse Nettet16. jan. 2024 · Inverse of Matrix If A is a square matrix and if there is a matrix B such that AB = BA = I, then A is said to be invertible and B is called an inverse of A. If there is no such matrix B, A is said to be Singular. In other words, matrix A is said to be Singular if it doesn’t have an inverse matrix. [4]
