Hi everyone. I'm back and happy to be back. I missed math. Anyways, I am taking a college Algebra class as it has been a while, and I definitely want to make sure I have a good foundation for higher maths. But, I have a conundrum. The teacher today gave this example that I thought I had solved...
Does anyone else want to weigh in here? I was hoping for more of a trail to start off on, so I can hunt and fact gather, and of course, save time. :) I'm game to go off in search of solutions myself too; I was just hoping for an idea as a starter, you know... like chain reading. But maybe this...
Thank you chiro for the quick response! You've given me some new angles to think over, and I will be sure to talk it over with him. Maybe he can look into setting off on his own. Thanks once again. :D
Another question to you (and anyone else who wants to chime in), are there still...
Hello! (I hope this is the right place for this thread.)
I have a family member who is in need of some help, and PF has always been incredibly helpful and amazingly insightful with all of my problems, so I figured that this is worth a shot.
So, as I said, I have a family member who is...
@Millennial: Hm, I haven't learned that yet or I somehow overlooked it. Today I'm going to try and go back to review in my textbook anyways, so I'll keep my eye out for that.
Could you give me an example using one of the identities or point me in the direction of a website (or thread on on...
@HallsofIvy: Thank you so much for your help. In particular, the equilateral triangle explanation really enabled my understanding. I drew everything out, figured that one of the legs is '1' because the perpendicular line bisects that side, and from the Pythagorean Theorem that the other leg of...

@Mentallic: Thank you very much. I spent a long time on it, but I think I did well. We'll see. *fingers crossed*
@Mark44: Ha ha! Good one!
Thanks everyone once again. I've moved on to logarithms which I have never encountered before, so I'll keep at it. I just wanted to say thanks again...
Woe. I actually got something right. What a pleasant surprise!
Thanks to Mentallic, Villyer, and Mark44! All of your explanations really helped and make a lot of sense. For some reason, this is something that I understand while reading, but it seeps out of my mind when I go to do the work. I...
Hello everyone! I'm back again. I hope you enjoyed your vacation from my questions! *teasing*
So, I'm working on discriminants right now. Although, I've been "working" on them for a while via the quadratic formula I just didn't know it.
I came across a point in my notes that I didn't...
Aaah, I see. Apparently, I have trouble with my factoring instincts. A.k.a. I need to factor things out the old fashioned way as opposed to doing mental math.
I see where I went wrong and even though my textbook seems to want me to keep the radicals all on one side, I think I'm going to make...
I managed to get the other problems right, but this one I've been fiddling with and can't seem to get the right answer.

For this I tried the method of...
Okay, thanks to everyone's replies I think I see several different ways of going about solving the problem. I have a couple other problems that I happened to get wrong with the same form, so I'm going to try this and see if I can solve them on my own now, but first, I'd like to make sure that I...
More fun with radicals!
...As for the problem, I tend to get problems with this same form (but with slight differences such as two separate binomials underneath individual square roots) wrong. I'm not quite sure what I'm doing wrong, so I was hoping for some help. :D

@20Tauri: Ha ha! I completely understand that. Maybe, it's something like math stage fright??
Thank you everyone for the reassurances. I was on vacation, so that is why it's been a while since you have heard from me. Now I'm back and ready to butt heads with my algebra quandaries once more...
