Question

40pts how many ways are there to find the inverse of a matrix??

Answer 1

The most common way to find inverse matrix is M−1=1det(M)adj(M)

Steps to solve inverse matrix are:
 
 1. Find determinant of given matrix.
 
 2. Find co-factor of matrix.
 
 3. Find adjoint of matrix.
 
 4. Formula for inverse = (Adjoint of matrix) / det (matrix)
