Simplify and verify for $p=1$ and $q=1$: $-3pq\times( -2pq)$.

 Given: $-3pq\times( -2pq)$.

To do: To simplify and verify $-3pq\times( -2pq)$, for $p=1$ and $q=1$.

Solution: 

$-3pq\times( -2pq)=-3\times-2\times p\times p\times q\times q=6p^2q^2$

For $p=1$ and $q=1$.

$L.H.S.=-3\times 1\times 1\times ( -2\times 1\times 1)$ and $R.H.S=6\times( 1)^2\times( 1)^2$

$\Rightarrow L.H.S.=6$ and $R.H.S.=6$

Thus, $L.H.S.=R.H.S.$
