You can try first finding the rational roots using the rational root theorem in combination with the factor theorem in order to reduce the degree of the polynomial until you get to a quadratic, which can be solved by means of the quadratic formula or by completing the square. There is a straightforward way to determine the possible numbers of positive and negative real zeros for any polynomial function. In most real-life applications, we use polynomial regression of rather low degrees: Degree 1: y = a0 + a1x As we've already mentioned, this is simple linear regression, where we try to fit a straight line to the data points. Solving matrix characteristic equation for Principal Component Analysis. For the given zero 3i we know that -3i is also a zero since complex roots occur in. Step 4: If you are given a point that.
