    Complex numbers: Prove that if ABS( (z1 - i*z2)/(z1 + i*z2) ) = 1, then...

    The full questions is: How do you factor with dividing these (binomials)? The equation I am working on is: |(z1-iz2)/(z1+iz2)|=1 I was told the next step is: |(z1/z2-i)/(z1/z2+1)|=1 I am branching off a different thread where a similar equation came up but I was told to make a separate...

    Rules for Reduced Row Echelon Form? (video left me confused)

    OK, so I bring this up because I find working with matrices could potentially be very useful. Watched a couple videos on how to put things in Reduced Row Echelon Form. The first video...

    Greatest Common factor from polynomial: 10x​^2 ​​+ 25x + 15

    I have no idea what I am getting wrong here... here is the problem: 3) Factor out the greatest common factor in the following polynomial. 10x​2​​+25x+15 I tried to do two things: 5(2x^2+1)(x+2) and 5[(2x^2+1)(x+2)] both are wrong, why?

    Parameters of Domain and Range: "For F(x) = 2/x, the domain cannot be 0."

    I have watched the first three videos from this: https://www.khanacademy.org/math/algebra/algebra-functions/domain-and-range/v/introduction-to-interval-notation I am confused as to all the rules that govern what the domain and range are of any particular function. So an example of a rule that...

    Pencils under username.

    What do they mean? My guess is that they represent the amount of posts you have. I have 2 pencils under my username. IDK exactly when this occurred, but I think it happened around the 50-55 number of posts marker.

    I forgot how to reverse foil (such as X^2 + 2X + 2)

    Take this equation: X^2+2X+2 If you reverse foil (I remember how to foil I think) would you get: (X+1)(X+1) ? Just a guess. X^2+X+X+1 Nope, that doesn't work.

    What would happen if...

    What would happen if you were to basically tie an overhand knot in space time? What would be the gravitational manipulation that it would have on objects? If you don't know what an overhand knot is, it's basically this: https://en.wikipedia.org/wiki/Overhand_knot this assumes there are no...

    Bell curve of the size of things in the universe.

    So assume that when looking at things through different size lenses (ex. microscope to telescope) assuming that if you represent this information as a graph, it would look like a bell curve.. There would be an average size of things in the universe compared to the different lenses that you use...

    Question about the function of this site.

    Can I use this site as a sort of playground to learn about different concepts of math? I ask because I am aware that I have been much more active in the past day than most people are. I don't want to overstep my bounds, but at the same time it would be really cool if I could use this site to...

    144=1+2x+3xy+4z where 3xy+4z=12

    144=1+2x+3xy+4z where 3xy+4z=12 Is this equation possible to solve? Is it as simple as: 144=1+2x+12 144=2x+13 131=2x 65.5=x Why? because playing around with abstract concepts is really fun.

    Thought experiment, don't know where else to put this.

    Where to start... Let's say you have a circle. This circle represents all possible outcomes (infinity). Within the circle, is another circle. What is within the inner circle represents the mean of all the possibilities (reality). That is the only thing that is within the inner circle. This...

    I'm taking this here because no one else understands what I am saying.

    OK, so I have stated this on 3 different forums and pretty much no one really knows what I am saying. So consider this a test of my sanity. The idea is that an unknown quantity could be literally anything. Anything includes things that either change or are a representative of infinity in some...
