### Re: Number Needed to Complete the Square

Note that

The two expressions have p^2 in it and 2ap if you put a = 7

So add a^2 = 49 and you have a perfect square.

As a general rule find half the middle coefficient (14/2 = 7) and square it (49).

Bob,

Thanks again. I will try a few on my own from the textbook.
I really don't understand how to upload pictures to this site.
Can you share the steps with me? Eventually, I will need to upload geometric and trigonometric pictures. Keep on mind that I don't have a computer or laptop. Can I upload pictures using my android cell phone?
Also, I will not reveal my name in an open forum. I will use my initials instead.

Let me see.

(14/2)^2 = (7)^2 = 49

The missing number that completes the square is 49.

You say?
