Question

Simplify : (a + b) (c – d) + 2bd Show the necessary working step also

Answer 1

First we have to Distribute:

⇒ (a) (c) + (a) (−d) + (b) (c) + (b) (−d) + 2bd

⇒ ac + −ad + bc + −bd +2bd

Then we have to Combine Like Terms:

⇒ ac + −ad + bc + −bd + 2bd

⇒(ac) + (−ad) + (bc) + (−bd + 2bd)

⇒ ac + −ad + bc + bd

∴ The answer is ⇒ ac − ad + bc + bd
