white liht is produced by blue light and what other liht? I think it's yellow, but I'm not even sure behind my reasoning. I could really just use some help on this; I've been trying to find a good website to explain the whole color theory, but so far what I've ...

How do I solve 2x^2-5x=0 by factoring, I tried taking the two out, but that doesn't seem to be working.

oh okay, yeah, that's the answer I got, but I'm just still really confused as to how they even got sqrt3. Thank you, though.

When solving for x by completing the square as in the equation 3(x-1)^2-1=0 should I add one to both sides then divide by three or add one to both sides then square root both sides? It makes sense to me to first divide by three, but if I do this, I'm not getting the ...

In school we're learning to use the quadratic formula. I understand how to use it and what its applications are, but I don't understand why sometime it's okay to simplify and sometimes it's not. For example, I got the result (-2 ± 2 square root of 6)/2. ...

no, I don't think I do. I tried completing the square and I'm just getting really weird numbers. :(

Two positive integers are in ratio 1:3. If their sum is added to their product, the result is 224. Find the integers. On my own, I came up with the formula 224 = x + 3 x + 3x^2 but it's not really working out. Could someone please help me?

I really don't understand this, I don't mean to be a pain, but I really need to understand this.

I have a test tomorrow and I really don't get this, please help me. "Use transformations and the zeros of the quadratic function f(x)=(x-6)(x+4) to determine the zeros of each of the following functions a) y=2f(x) b) y=f(2x) c) y=f(0.5x)" I am so lost, I don'...

Please, I still need help with this. I need to make tables of values for both horizontal and vertical stretching, but I wasn't in class and missed the lesson. I don't really understand how to get the values; at first I figured you'd get the value of y by just ...
