x^2+14x+c

1. The coefficient of x is 14.
2. Multiply that coeficient 14, by .  Get 7
3. Square 7. Get 49

That's it.

x^2+14x+c then becomes x^2+14x+49 which factors as (x+7)(x+7)
which can then be written as (x+7)^2, which is the square of a
binomial.

x^2+14x+c
In order to do this
you need to take half of the middle term and square it. That will give you c.
14/2 = 7 7^2 = 49
See if that works for you.
