How To Solve Quadratic Functions In Simple Way

Solving Quadratic Equations

REMEMBER, that in a quadratic equation:

1. We are trying to find out the solution to x which makes the left hand sideof the = sign equal theright hand side of the = sign
2. There will always be two solutions. This is because the x is to the power of 2
3. It is always necessary to check the solutions to make sure that you really do have the correct answers and have not made any mistakes along the way
4. A negative number multiplied by a positive number will always be a negativenumber whereas a positive number multiplied by a positive number will be apositive number
5. In some questions they substitute the letter x for another letter although in essence you use the same method for finding the value of that letter

SKYNET 101: Linear Separability

One of the areas I particularly want a crack at, one of these days, is videogame AI. As an undergrad, I worked in an AI research lab, and I played with a whole bunch of systems. I’ve used and implemented expert systems, neural networks, fuzzy logic, genetic algorithms… If the technique existed around 2000, I’ve at least read a paper or two about it. Since I’m still being frustrated by my own game code, I decided to take a break and talk about my ideas on ways to manage game AI. Specifically, I’

Public Education, BVSD, and Me

I don't know about you, but I keep hearing on radio talk shows and in the media all about "the state of public education." I've been hearing about this for years, probably ever since I was a kid. I personally went to seven elementary schools in five states, and I could attest to the fact that there was a difference in the quality of education at each place. Sometimes I would find myself moving to a place where I was ahead of the apprpriate grade, and sometimes I'd find myself behind. The si

A Real Version for the Square root of -1

A Real Version for the Square root of -1 The above was conceived from the first letter of Imaginary, because the number representing the square root of -1 doesn't exist on the real number line. Pythagorus and other great Mathematicians were dumbfounded by the meaning of , yet in todays higher level Maths, is now taken for granted. However, it's true meaning seems to have been bypassed as our interpretation of it still allows history to dominate our thinking basis re . I actually dis

Re-visiting non-polynomial factorization

It has been a while since I talked in detail about what is my most revolutionary result since it overturns most of modern number theory by highlighting an error that came into the field in the late 1800's. The overview of the result is that instead of factoring polynomials into polynomial factors, which is boring anyway, like x2 + 3x + 2 = (x+2)(x+1) I factor polynomials into non-polynomial factors, which is the additional clever step that reveals a remarkable and deep error in "core" mathema
