Identifying perfect square form (video) | Khan Academy
Sal shows how we can identify that a trinomial has the "perfect square" form. Video transcript - [Voiceover] We wanna figure out what AX plus B squared is, and I encourage you to pause the video and figure out what that is in terms of capital-A and capital-B.

However, in the "Practice: Perfect Squares" exercise, a solution says that 14x (the center term of x^2 + 14x + 49) is twice the root of 1x^2 and 49, implying that A is the coefficiant AND the variable of 1x^2.
Factoring using the perfect square pattern - Khan Academy
You are confusing difference of 2 squares: (a-b)(a+b)=a^2-b^2 and perfect squares: (a+b)(a+b) = a^2+2ab+b^2. Note" if "b" is negative, then you get (a-b)(a-b) = a^2-2ab+b^2. If you aren't sure you picked the right one to use, multiply your 2 binomials using FOIL to see if your result matches the polynomial you factored.
