9 , 46, -30, -30, -25
11, -30, 95, 36, -10
14, 13, -15, 57, -11
-6, -25, -10, 1, 28
Im also New to the forum and dont know how to properly post a matrix, sorry, But aside from that
How do i approach this problem? as far as i know to find the spanning set i find my reduced row-echelon form matrix, and Sort out the dependent and independent columns, but this matrix is rather large and ugly which makes me feel like theres a trick to this that involves MUCH less work than RREF.
