01 - Simplify Square Roots with Factor Trees in Algebra (Radical Expressions), Part 1

In this lesson, you will learn what a square root is and why they are important in algebra. We will learn to simplify algebraic expressions that involve square roots by using the concept of a factor tree.

A factor tree is the process of determining all factors or a number or algebraic expressions. Once we write the factor tree, we can find the square root of the expression by looking for pairs of numbers in the "bottom" factors of the tree.

My professor went over this whole video in 5 minutes in class then moved on to more complex curriculum leaving me lost for the next 3 hours. I need the long form explanation like this video because I need the "why you need to do this" not just "how to do this" explanation to learn it. I love this format, thank you

Many of us were lost in high school math due to a rapid curriculum. Your method provides depth and understanding by repeating fundamentals. Thank you, sir.

Hey, man. I really appreciate you putting these videos out there. I’m 31 and I’ve always been discouraged by math until I found videos like this. Your channel with all of these other channels is like a modern day Library of Alexandria. So, thank you for all that you do to educate.

I'm 23 trying to learn math from the ground up. Been using khan academy so far and got stuck on this section and then I found this video. Thank you it helped so much! :)

this guy is a great teacher . I have learned so much from him in a very short time, an i am 78 yrs old.I will have my grand kids watch and learn from him.

Sir i respect you a lot for making this video. My school and tusion teachers only explained this on the surface and i always wanted to understand what was going on behind the scene. They all explained just the steps, like they were reading from a script but you made sure to explain what your students really needed to know.

I wish you were my math teacher when I was young. You broke it down by detail to detail. Thank you so much.

[borowczyk]

These are the absolutely best math videos on YT. Beautifully explained.

Having access to a teacher like you you is such a relief. I have to sit through a 4 hour online lecture every week wasting my time with a guy who simply does not know his stuff. Hopefully he will watch your videos :)

It's absolutely new to me, I wonder in which grade was I suppose to learn this. Got it. 🙏 Mathematics made easy.

[jamesb]

I have just went back to college after many years and I LOVE THIS INSTRUCTOR!!!!

[abdesay]

That's what I can call a real maths teacher. Thank you

[ikamaulizan]

Thank you. I am 27 y/o studying for gmat and this rings the bell of what i’ve learnt during high school.

[daeshandarosa]

This man is a genius! I probably wouldn't be able to explain this to someone who doesn't know it in the same understandable way he did! Bless you! T-T

[jchrg]

You are never too old to re-learn it again, or even come to new insights that actually work, haha...it's all about keeping calculating...
We don't discover, we just document as humankind

[TheCarabailey]

Unbelievable... At the end of this Video, All of the equations made sense. Thank you!

[joyunday]

You're far better than actual school.
Thank you for sharing your knowledge.

[lyasweetheart]

i love the fact this dude just roasted the heck out of school textbooks.

[rauldempaire]

What a difference a good teacher makes!

[weeredvixen]

A massive heart felt thank you for taking the time to explain this fully and in depth.
