Question

I need help with this

Answer 1

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)
