Find the inverse of the matrix if it exists

WebAssuming it doesn't begin with 0, divide every value in the augmented matrix's first row by the first number to get 1. Then, without actually changing the first row, take the first row multiplied by the negative of the first value of a row below it, and add it to that row, so that every value under the first 1 is a zero. WebExample. We are going to calculate the inverse of the following 2×2 square matrix: First, we take the determinant of the 2×2 matrix: Now we apply the formula of the inverse matrix: And we multiply the matrix by the fraction: So the inverse of matrix A is: As you can see, inverting a matrix with this formula is very fast, but it can only be ...
