Can someone verify this:
|1 -1| = P
|-2 1|
|-1 -1| For P^-1, i got this.
|-2 -1|
|-1 -2| My solutions manual, says this is the answer.
|-1 -1|
My solutions manual has been wrong before. The way i got my answer was to put the identity matrix to the right of P and solve for the right side and get the left into the identity.
|1 -1|1 0| = P
|-2 1|0 1|
|1 0|-1 -1| = P^-1
|0 1|-2 -1|
Thanks
