2. (6 points) The multiplier is 6, the multiplicand is 140 less than the product, the multiplication equation is
【Solution】Let the product be $x$, then the multiplicand is $x-140$,
$$
\begin{array}{l} 
6(x-140)=x \\
6 x-840= \\
5 x=840 \\
x=168 \\
168-140=28
\end{array}
$$

This multiplication equation is: $6 \times 28=168$
Therefore, the answer is: $6 \times 28=168$.
