5a²b-5ab²-13a²b-13ab²
= -8a²b-18b²a= -2ab(4a+9b)
= -8a²b-18b²a= -2ab(4a+9b)

Here,
5ab(a-b) - 13ab(a+b)
= (5a^2b - 5ab^2) - (13a^2b + 13ab^2 )
= 5a^2b - 5ab^2 - 13a^2b - 13ab^2
= -8a^2b -18ab^2
= -2ab(4a + 9b)
5ab(a-b) - 13ab(a+b)
= (5a^2b - 5ab^2) - (13a^2b + 13ab^2 )
= 5a^2b - 5ab^2 - 13a^2b - 13ab^2
= -8a^2b -18ab^2
= -2ab(4a + 9b)
