Question 30980: I don't understand how to do this problem:
(root)3x(squared) - 2x - 2(root)3 =0
I keep getting x=2root3 as my answer, but it's wrong. My teacher gave me the answer root3(+-)root21 / 3
How do I get that answer?

Question 29943: hi,
I was wondering if you could help figure how to work a couple of radical equations. I tried them tons of different ways but I don't think I have the right answers. I also have problems with 4th and 5th roots
1) square root of 1/2 plus 3square root of 3/8. I got square 2 over/divided by 2 plus 3square root 6 over/divided by 2.
2) 5th root of 1/8. I got 5th root of 4 over/divided by 2.

Question 31715: Please help me simplify this problem: square root of 8 divided by 2 times the square root of 5 plus the square root of six.
Sorry, I do not know how to make a square root sign so I could not type the problem out but I will type it out without the square root signs to give you some idea. The square root signs go over the 8, 5, and the six:
Ignore the ! (exclamation mark)
The six is supposed to be part of the denominator!
Thanks ahead of time for helping me!

Question 32069: Hello. Here is my question. I know how to solve this problem if it didn't have the second square root in front of the "x" on the left of the equality. I would show you work but all I have been able to do is move the -1 over to the left side (as a +1). After that, I can't do anything else until I get rid of the squareroot in front of the "x". Here is the problem:  .
Thank you for any help you can provide.

Question 32498This question is from textbook college algebra
: These probably seem pretty simple, but I'm sorry, I still need help. A little explanation helps me greatly. I appreciate your help and time.
1)Is square root x squared =x an identity (true for all values of x)?
2) For the equation x-square root x=0, perform the following: a) solve for all values of x that satisfies the equation. b) Graph the functions y=x and y=square root x on the same graph (by plotting points if necessary). Show the points of intersection of these two graphs. c) How does the graph relate to part a?This question is from textbook college algebra

Question 27239: ok i had this test and thers this one problem that says simplify,
the problem is the 6th root of 81x^10,
its hard to type out symbols but it'd be a square root sign only 6 out side of it, and inside is 81x^10. I put the answer as x outside of 6th root of 81x^4,
whats the answer
