SpletWe can generalize the least squares method to other polynomial curves. To find the quadratic equation $y=a x^2+b x+c$ that best fits the points $ (-1, −3)$, $ (0, 0)$, $ (1, −1)$, and $ (2, 1)$, we first write the matrix equation $AX=B$ that would result if a quadratic equation satisfied by all four points did indeed exist.
