Question 122361: I am having trouble. I transferred from a school where they plop a book in front of you and you just do the problems. Everyone was in different books, and the teacher never left his seat, and he never spoke about anything related to the class. They didn't even give me the basics. I learned as I went. The school I am in now requiers that I know this because I am in Algebra 1. Is there a book or site that can help me get the basics? Thnx alot for your help.

Question 128130: I am a homeschooling mom. I have come across these problems. I don't understand how it works. I want to be able to understand in order to teach my kid the right way.
Here are the problems in one 'sentence': ( if you see the dashes between these numbers - that is division. And..as for the # 3 and # 4 ...I have been unable to get the denominator to look the way it should... under the first combination it is divided by 2x; and the second combination, it is divded by an x.
1.
3/2 + 3/x
--------- =
2+4/x
2.
(3/2+3/x)/(2+4/x)=
3.
(3x+6)/(2x+4)
----- ---- =
2x x
4.
3x+6 * 2x+4
---- ---- =
2x x
5.

-----------

I would very much appreciate your explanation and how you arrive to the answer..and please make it in layman's terms. Thanks.

Question 129688: x^2-2x+26=0 I have to factor this with complex numbers.
so I tried but I'm not sure if I did it right or if I can reduce my square root by 2. Here are the steps I took.
x={-(-2)+-the square root of -2 -4(1)(26)}/2
x= {2+- the square root of -108}/2
x= {2+- the square root of 108i}/2
x= 2/2 +- the square root of 108i/2
x=1+- the square root of 108i/2
and that's where I'm stuck at can I divide 108 by 2 even though 108 is in a square root?
