1. [Show all steps! Otherwise, no credit will be awarded.] (10 points) Write the matrix as a product of elementary matrices. Note: You must show all elementary row operations and label the steps (e.g., R₁ + 2R₂ R₂) next to each new matrix. Also, make sure to write A in terms of the new product and check your answer using matrix multiplication to make sure your matrix product gives you A. [02 3-4 2. [Show all steps!
