Question: Consider the matrix > 4 ((2.1,-1)|(2,2,p)); A:= where p is a parameter. (A) Investigate whether the left inverses of A exist for any value

Consider the matrix > 4 ((2.1,-1)|(2,2,p)); A:= where p is a parameter.

Consider the matrix > 4 ((2.1,-1)|(2,2,p)); A:= where p is a parameter. (A) Investigate whether the left inverses of A exist for any value of the parameter p. EXPLAIN why yes or why not. (B) Find all left inverse matrices of A for all those values of p when the left inverse exists. (NOTE: to check your solutions you need to apply the command "simplify" to the result of your calculations).
