To factor the given polynomial \(3x(y - 3) + 7(y - 3)\), we can identify a common factor in both terms.

Both terms include the factor \((y - 3)\). Therefore, we can factor \((y - 3)\) out:

\[
3x(y - 3) + 7(y - 3) = (y - 3)(3x + 7)
\]

So the polynomial factored completely is:

\((y - 3)(3x + 7)\)

The correct choice is:

A. \(3 x (y - 3) + 7 (y - 3) = (y - 3)(3x + 7)\) (Factor completely.)
