Question

Simplify: (a + c)(c + d) + (a - b)(c + d) + 2(ac + bd)

Answer 1

Answer:

4ac

Step-by-step explanation:

Given,

(a+b)(c-d)+(a-b)(c+d)+2(ac+bd)

now we multiply each other,

      =a(c-d)+b(c-d)+a(c+d)-b(c+d)+2(ac+bd)

          =ac-ad+bc-bd+ac+ad-bc-bd+2ac+2bd

             =2ac-2bd+2ac+2bd

                 = 4ac
