Answer 2

Step-by-step explanation:

1. (a-b)(2a+4b)

=2a²+4ab-2ab-4b² its simple multiplication

=2a²+2ab-4b² hope it was helpful

=2(a²+ab-2b²)

2.(3x+2y)(3y-4x)

=9xy-12x²+6y²-8xy

=-12x²+xy+6y²

3.(2m-l)(3l-m)

=6lm-2m²-3l²+lm

=-2m²+7ml-3l²

=-(2m²-7ml+3l)

4.(k+3m)(3m-k)

=3mk-k²+9m²-3mk

=9m²-k²
