Answer 1

Answer:

-72x^3y+ 48x^3y^2 - 48x^2y^2

Step-by-step explanation:

Firstly let's find products of each term

3xy(16xy-4x^2)

=48x^2y^2-12x^3y ------1

6y(-14x^3+8x^2y)

= -84x^3y+48x^3y^2 ---- 2

Now, let's subtract 1 from 2

( -84x^3y+48x^3y^2)-(48x^2y^2-12x^3y)

= -84x^3y + 48x^3y^2 - 48x^2y^2 + 12x^3y

= -84x^3y+ 12x^3y+ 48x^3y^2 - 48x^2y^2

= -72x^3y+ 48x^3y^2 - 48x^2y^2
