Just replace the value of x with A in the given function.
Answer is 2A^2-3A+5I. Here in the function 5 has no variable so when written in matrix form I will be added( identity Matrix) because it doesnt change its value and to add the equation everything need to be in matrix form.

But do we have to solve that equation in matrix form or leave it as it is
it depends on both marks as well as the question. If A matrix is given and the question is of higher marks then you need to solve it.
if A is not given do we have to let matrix A = a. b c d
no
okk
because you are not given the order
ok
