From the Algebra 1 course by Derek Owens

Excellent explanation. It amazes me how many people on YouTube explain things better than teachers in a classroom.

I have two students whom I am helping with algebra since they are home bound due to medical issues. I have looked at many different video tutorials, and yours are by far the most helpful. Thank you on behalf of my students for making these lessons available. Your lessons are so complete with clear and easy to understand instructions and a variety of problems that I don't need to look any further. Thanks again. I really do appreciate you doing this.

this is sooo helpful and your handwriting is amazing...i just spent a good 40 mins viewing your radical videos to study for my test tomorrow thanks so much! im totally confident i will do well:)

thank you for explaining better than my teacher. :)

An internet teacher might be more real than a "real teacher" !

Think of it like this: 6 apples plus 5 cars does not equal 11 apples. Also, 6 apples plus 5 cars does not equal 11 cars. Think about that, and then try to apply the same concept to mathematical entities.

6a + 5a is 11a.
But 6a + 5b = ... Those can't be combined.

6 root 6 + 5 root 6 = 11 root 6
Buy 6 + 5 root 6 = .... Those can't be combined.

Hope that helps!

Very thorough. A wonderful refresher course.

I recently had to move from a private school to a public school, and the level of math was tremendously dumbed down. I forgot a lot of stuff, granted, I was still making A's, but I would personally like to hold onto that information.

TY made me remember everything that I forgot from last year

[denyelledalisay]

your a Savior for engineering students having a hard time understanding these stuffs :)

You just made my day. Finally an understandable tutorial!

at 2:29 he takes the perfect square of 4 and moves it to the other side joining the other 4, but why does it become 2? Shouldn't 4x4 be 16? When you move the perfect square to the other side do you add them?? Help pls

[ロプノールs]

thank you to teach me how to solve sir,

[GabbiPretzels]

could that last one reduce to the square root of 1 since 2/2=1 ?

[lambotran]

my god thanks for saving me, my teacher can't teach at all T.T

[cfloveland]

No, because it's radical 2 over the number 2, not 2/2 or radical2/radical2, so they're not 'like terms', and so you can't reduce it. XD

[currynrice]

since its only you and nobody else its easier to concentrate

[BlooBewwiShwimp]

You skipped a step on how the 4 in 4x3 broke into 2

Thanks I’m in seventh grade algerbra one and I have to do work over the weekend and I forgot how to add and subtract uneven radical. 1 LIKE FORM ME FOR SURE!!
