 Homework Statement:

Hi! I need help with my homework.
I need to prove that the matrix below is a tensor.
 Relevant Equations:
 ## T'_{ij} = T_{rs}\frac{\partial x^r}{\partial x'^{i}}\frac{\partial x^s}{\partial x'^{j}} ##
I have the matrix
$$
A = \left(\begin{array}{cc}
y^2 & xy\\
xy & x^2
\end{array} \right)
$$
I know that to prove that the matrix is a tensor, it transform their elements in another base. But I still without how begin this problem.
Help please! Thanks.
