Quadratic Zeros II

This app allows you to adjust the zeros of a quadratic function to match the factorization, then verify them with the general function.  The examples include more challenging factorizations (a not equal to 1).

Least Square Linear Regression

Move the points then press the play button.  The potential energy of the (zero natural length) springs is proportional to the sum of their length. Equilibrium will occur when the regression line is found
