Perfect square factorization intro (video) - Khan Academy
This video is trying to show you that there is a pattern that you can use to factor a perfect square trinomial. -- If you multiply: (a+b)^2, you always get: a^2+2ab+b^2 -- You can leverage that pattern to reverse the process.

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.
Worked example: completing the square (leading coefficient ≠ 1)
Or you could look at the last video on constructing perfect square trinomials. I encourage you to square this and see that you get exactly this. And this will be equal to 75 plus 25, which is equal to 100.

Factoring perfect squares - Khan Academy
Let's just think about what happens when we take the perfect square of a binomial, especially when the coefficient on the x term is not a 1. If we have ax plus b squared, what will this look like when we expand this into a trinomial?
