Web$A^2 + A + I$ is invertible (with inverse $I - A$), and $A^2$ is nilpotent (as $(A^2)^2 = A(A^3) = 0$), and the sum of a unit with a commuting nilpotent is again a unit. Indeed, $((A^2 + A + I) + A^2)(I - A) = I + (I - A)A^2 = I + A^2$, which has inverse $I - A^2$, so $(2A^2 + A + I)^{-1} = (I - A)(I - A^2) = I - A - A^2$.

WebSep 17, 2024 · Solution. Consider the elementary matrix E given by. E = [1 0 0 2] Here, E is obtained from the 2 × 2 identity matrix by multiplying the second row by 2. In order to carry E back to the identity, we need to multiply the second row of E by 1 2. Hence, E − 1 is given by E − 1 = [1 0 0 1 2] We can verify that EE − 1 = I.

WebMar 5, 2024 · To find the inverse of a matrix, we write a new extended matrix with the identity on the right. Then we completely row reduce, the resulting matrix on the right will be the inverse matrix. Example 2. 4. ( 2 − 1 1 − 1) First note that the determinant of this matrix is. − 2 + 1 = − 1. hence the inverse exists. WebLet A be an m n matrix. Then, AT is by de nition an n m matrix. Since A = A T, the dimensions of A must be the same as the dimensions of A. Therefore, m n must be the same as n m, and so we can conclude that m = n.
