See the attached screenshot for the question - too complex to type out.

Consider the matrix: 1 A=4 7 OOUINJ @0303 Use Gaussian elimination to: (1) Find a lower triangular matrix L E M3(R) and an upper triangular matrix U E M3(]R) such that A = LU. (2) Find an invertible matrix P E M3(R) so that PA is the reduced echelon form of A. You may leave your answers as products of matrices in this
