Thank you for posting your question here at I hope the answer will help you. Feel free to ask more questions.

The answer should be A which is square the binomial. 

The second method is a shorter alternative to FOIL. The way we use the shortcut is to follow three simple steps. Step 1 Square the first term of the binomial. Step 2 Multiply the first term and last term of the binomial together and then double that quantity (in other words multiply by 2).
