Okay, let me explain.

Basically, you need to complete the square.

So you have,
x^(2)+14x+__________ to equal a perfect square.


Your middle term is 14. So, what you need to do is divide fourteen by 2 which equals 7. What does 7*7 or 7 squared equal? It equals 49.


The missing constant term is 49.


I hope this helped; feel free to ask any follow-up questions.
