Take half of the x coefficient -14 and square it to get %28-14%2F2%29%5E2=%28-7%29%5E2=49


So the missing term is 49 which means that x%5E2-14x%2B49 is a perfect square trinomial.

Divide the coefficient on the term by 2. (that would be the "b" in ) Square the result. Put that result in as the missing third term of your trinomial.

If you ever have a lead coefficient different than 1, then you need to divide the whole polynomial by the lead coefficient first.

In general, is a perfect square if and only if
