Solving an Equation Containing Two Radicals - Example 3

[chivyp]

you made this so much easier to understand than when my professor was explaining it. YOURE MY HERO! thank you!

[lucilleavenido]

hi, just wanna know... in ur prev. vids, you'd cancel out (by either subtracting or adding) the freshly squared radicals on both sides... but now u subtracted -19 in this video. why? bc i did mine but i cant get an answer because i answered 19 out with +1 bc (2x-1) so +1. right?

Thank you! Showing all your work was very helpful, that's a great habit!! You definitely helped me out! :)

[Sheaffer]

Thank you very much. I was struggling with this. Your explanation made it easy.

[aprilburbank]

Thank you for your help. Do you have any site where you can work a problem and explain the steps? I am getting stuck on squaring the radicals.

[TheIrbe]

Thank you so much. Had trouble doing this eith two radicals, but it looked so easy when u did it.

[patrickjmt]

it is a shame your algebra teacher can not give a better answer than that.

[NakaharaSunako]

Thanks a bunch this helped a lot in my notes, especially when I wrote each step you did with a different color so I could remember what happened.

[Reda]

I learned so much from this! Thank you! Saved my life!!!

[Scoobydoo]

Amazing explanation, 1000 times better than my high-school teacher

[Ms_Spark]

Seriously thank you!!! I wrote all of these in my math notes!!! It really helps a lot :)

Thanks for the help. I know I need to expand them, but I couldnt get it because square root multiply to square root just cancels the square root. I thought it wasnt that simple and never went through the step end up giving up and just watch your video. I was right but I wasnt sure it would be the right way. Anyway thanks for the help man. I appreciate it, seriously

[sadamsaman]

great it was the only resources for me that i found many problems in math really helps me out.

I guess learning online isn't a bad experience, it just depends on the type of tutors. this was really helpful. I understood it better than my teacher's explanations (even though she's good) but THANK YOU SO MUCH FOR THIS!!!...I'M SO HAPPY I UNDERSTOOD IT AT ONCE

I don't get the foil method in radicals for example if I foil this I get (4√x-4)^2 I get 16-8-(4x-4

[Brisun]

why is it -4 when ur mult. -2*-2 in the second step isnt it pos 4?

[kellygivens]

Thanks. I am having a hard time foiling the expressions. You make it look easy.

[cnaatwork]

Great video! But what if the index of the radicals is 4? I'm lost

[Ms_Spark]

@patrickJMT you need a video on solving radical inequalities.

[MrTimbojim]

Thank you, just needed a little bit of clarity ;)
