T is the matrix
\begin{bmatrix}
2q &0 \\
p& p
\end{bmatrix}
They asked to find the determinant of T which I did and that is 2pq.
Then they said, if q= 1/2 and p=4, find the inverse of T which i did and it is
\begin{bmatrix}
1 &0 \\
-1& 1/4
\end{bmatrix}
Now the question states: ''If T is singular and p is not equal to q, state a pair of values from p and q.
All I know is that singular means the determinant of T equal to 0.
I don't understand what I'm supposed to do here, am I supposed to just guess a random pair of numbers?
If I could do that I would just say 0,0... but then I just realized I can't do that.... as they give the condition... ahhh please help
Edit: Actually since the determinant in itself is 2qp, can I just say q= 1 and p = 0 thus giving me 2(0)=0 showing that the matrix is singular?
