Step 1
Let's call the matrix A: $$ A = \begin{bmatrix} a & b \\ c & d \end{bmatrix} $$ The determinant of a 2x2 matrix is calculated as follows: $$ \det(A) = ad - bc $$ Now, let's determine if the matrix has an inverse. A matrix has an inverse if and only if its Show more…

Given the matrix (a) does the inverse of the matrix exist? Your answer is (input Yes or No): (b) if your answer is Yes, write the inverse as
Inverses of Special Matrices Find the inverse of the matrix. $$ \begin{array}{l}{\left[\begin{array}{ll}{a} & {-a} \\ {a} & {a}\end{array}\right]} \\ {(a \neq 0)}\end{array} $$
