Question

Please help me in this question and write the steps. Please circle the answer so that I can understand the answer. If you write by hand, write clearly so that I can read the numbers and specify the answer to each question so that I can understand which answer is related to which question. I appreciate you for understanding.

Use the fact that if \( A = \begin{bmatrix} a & b \\ c & d \end{bmatrix} \), then \( A^{-1} = \frac{1}{ad-bc} \begin{bmatrix} d & -b \\ -c & a \end{bmatrix} \) to find the inverse of the given matrix, if possible. Check that \( A A^{-1} = I_2 \) and \( A^{-1} A = I_2 \).

Given matrix:
\[ A = \begin{bmatrix} 4 & -5 \\ -3 & 2 \end{bmatrix} \]

---

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

- A. \( A^{-1} = \) [Box for answer]
  (Type an integer or a simplified fraction for each matrix element.)

- B. The matrix does not have an inverse.

(Note: The problem guides through calculating the inverse of a \( 2 \times 2 \) matrix, using the standard formula, and verifying it by checking if it results in an identity matrix when multiplied both ways.)
