Question

Factor this polynomial by grouping the terms: ac + bc - ad - bd
A. (a + b)(c + d)
B. (a - b)(c + d)
C. (a - b)(c - d)
D. (a + b)(c - d)

Answer 1

option d ?
 ac + bc - ad - bd
= ac - ad + bc - bd
=a(c-d) + b(c-d)
= (a+b)(c-d)

Answer 2

C(a+b) - d(a-b) =0
(a+b)(c-d)=0
Option D is your answer

Hope it's help you friend ☺️
