$2 x^{2} y + 3 x - 8 x y - 12$ $2x^2y+3x-8xy-12$

Explanation:

The product is written (2xy + 3 )(x - 4)

To expand the brackets, each term in the 2nd bracket is multiplied by each term in the 1st bracket.

That is $2 x y (x - 4) + 3 (x - 4)$ $color(red)(2xy)(x-4)+color(red)(3)(x-4)$

$\Rightarrow 2 x^{2} y - 8 x y + 3 x - 12 is the product$ $rArr2x^2y-8xy+3x-12" is the product"$
