Given Equation is 30xy - 12x + 10y - 4 can be written as

                              2(15xy - 6x + 5y - 2)  --------- (1)

 Factors of 15xy - 6x + 5y - 2 = (15xy + 5y) + (-6x - 2)

                                                = 5y(3x + 1) -2(3x + 1) 

                                                = (3x + 1)(5y - 2) ----- (2)

Substitute (2) in (1), we get

30xy - 12xy + 10y - 4 = 2(3x + 1)(5y - 2).

Answer 2
