Does … WebFrom the original equation, you also know that A 2 = 4 A + 4 I, so A + I = A 2 4. Since A 2 is invertible, and dividing a matrix by its scalar does not affect its invertibility (determinant can't become 0, preservation of dimensions etc. remains the same), you have that A + I is equal to an invertible matrix. Hence, A + I is invertible. Share Cite kathevans731 gmail.com

"WebAn invertible matrix is a square matrix that has an inverse. We say that a square matrix is invertible if and only if the determinant is not equal to zero. In other words, a 2 x 2 matrix is only invertible if the determinant of the matrix is not 0. If the determinant is 0, then the matrix is not invertible and has no inverse. 2x2 Invertible matrix " - Check matrix invertible
