Thank you so much for explaining this using the "PAF" technique. What a blessing that has been for me.

Wow, seriously best maths videos on YouTube, very helpful

[idrissaturay]

Thank you professor. The lectures are really vivid but what I think you should add is giving a brief explanation of the topics you're treating. Like saying something about Quadratic, linear equations...

This is great to learn. Now I don't have to use the quadratic formula for these types of trinomials.

I have a question what if my teacher a big sum for example... It's a bit hard to use the "PAF" technique.
