Simplifying the Expression (a+b)(c-d)+(a-b)(c+d)+2(ac+bd)
This article will guide you through the process of simplifying the algebraic expression: (a+b)(c-d)+(a-b)(c+d)+2(ac+bd).
Step 1: Expanding the Products
We begin by expanding the products using the FOIL (First, Outer, Inner, Last) method:
- (a+b)(c-d) = ac - ad + bc - bd
- (a-b)(c+d) = ac + ad - bc - bd
Step 2: Combining Like Terms
Now, let's substitute these expanded terms back into the original expression and combine the like terms:
(ac - ad + bc - bd) + (ac + ad - bc - bd) + 2(ac + bd)
= ac - ad + bc - bd + ac + ad - bc - bd + 2ac + 2bd
= 4ac
Simplified Expression
After combining all the terms, we are left with the simplified expression: 4ac.
Therefore, the simplified form of the expression (a+b)(c-d)+(a-b)(c+d)+2(ac+bd) is 4ac.
