![**Find the Inverse of a Matrix**
To find the inverse of the matrix \( A \), if it exists, use the algorithm for finding \( A^{-1} \) by row reducing \([A \, | \, I]\).
**Matrix \( A \):**
\[
A = \begin{bmatrix}
2 & 2 \\
2 & 5
\end{bmatrix}
\]
**Steps:**
1. **Set up the Augmented Matrix \([A \, | \, I]\):**
- The matrix \([A \, | \, I]\) combines matrix \( A \) with the identity matrix of the same size.
- Input the resulting matrix after augmenting.
\[
[A \, | \, I] = \begin{bmatrix}
2 & 2 & 1 & 0 \\
2 & 5 & 0 & 1
\end{bmatrix}
\]
**Instructions:**
- Enter an integer or simplified fraction for each matrix element.
This process will help identify whether the inverse matrix exists and, if so, allow you to calculate it effectively by using row reduction techniques.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2432691a-c29a-4a02-b85a-93b716867369%2Fddd76e94-f0fe-494c-aaa9-c69b6652e759%2Fadme9fu_processed.png&w=3840&q=75)
