Answer:
12x²y² +2xy -2
Step-by-step explanation:
The distributive property is used to multiply polynomials.
(3xy -1)(4xy +2) . . . . . . . . . . . . . given
= (3xy)(4xy +2) -1(4xy +2) . . . . multiply the 2nd by the terms of the 1st
= (12x²y² +6xy) +(-4xy -2) . . . . here are those products
= 12x²y² +2xy -2 . . . . . . . . . collect terms (6xy-4xy = 2xy)
