Solution:
Given expression 28xy - 154x + 20y - 110
In order to find factors,we need to split the given expression
28xy - 154x + 20y - 110 = 7x(4y -22) + 5(4y - 22)
28xy - 154x + 20y - 110 = (7x + 5)(4y - 22)
28xy - 154x + 20y - 110 = 2(7x + 5)(2y - 11)
The factors are 2(7x + 5) and (2y - 11)
Summary:
The factor of 28xy - 154x + 20y - 110 is 2y - 11
