Educação pode mudar sua vida

​Dadas as matrizes $A = \left(\begin{array}{cc}1& -1\\ 2& 3\end{array}\right)$ e $B = \left(\begin{array}{cc}0& 1\\ 3& 8\end{array}\right)$ então, calculando-se $(A+B{)}^2$, obtém-se:
a) $\left(\begin{array}{cc}1& 0\\ 60& 121\end{array}\right)$
b) $\left(\begin{array}{cc}1& 0\\ 25& 121\end{array}\right)$
c) $\left(\begin{array}{cc}1& 0\\ 4& 8\end{array}\right)$
d) $\left(\begin{array}{cc}1& 60\\ 1& 121\end{array}\right)$
e) $\left(\begin{array}{cc}1& 1\\ 1& 1\end{array}\right)$
