Answer 1

`2(6x^2y^2+xy-1)\\`

Explanation:

We are to find the product of the given expression. Given the expression

(3xy - 1) (4xy + 2), th product is derives by simply opening up the bracket as shown below;

`= (3xy - 1) (4xy + 2)\\\\= 3xy(4xy)+2(3xy)- 1(4xy)-1(2)\\\\= 12x^2y^2 + 6xy-4xy-2\\\\= 12x^2y^2 + 2xy-2\\\\bringing\ out\ the\ common\ factor;\\\\2(6x^2y^2+xy-1)\\\\`

The expression 2(6x²y²+xy-1) gives the required product.
