We first find ** A^{2}**, for which we multiply

Let us now find **3 A**, for which multiply each element of

Now, to find **2 I** we consider the identity matrix of order

To find ** A^{2}–3A+2I**, consider all three matrices obtained in previous steps and add/subtract them.

**Answer:** The value of ** A^{2}–3A+2I** is:
