Document Summary

When you are trying to find the roots of a function, the function needs to be in the form f(x) = 0. x^(2) - a = 0. Lets say you have a problem such as: This basically means that if you were given a square with each side of length x, the area of it would be a. However for that technically to happen side 1 would need to be of length x, and side 2 would need to be of length (a/x). This is because if you were to multiply them, they would give you an area of a. You can make the rectangle more square by changing the x value to the average of the two sides. By changing the x value you, you in hand change the other side as well, and so overall it makes the rectangle, more square . The formula for changing the x value is: x+ = (1/2)*(xc + (a/xc))
