PreCalculus 3: Graphing Polynomial & Rational Fcts (12 of 29) Using Synthetic Division to Find Roots

In this video I will use synthetic division to find the roots of y=x^2-2x+3 (if any).

I think it seems to use the quadratic formula (determinant) gives you quicker solution from the get go just if there is any solution but surely sometimes you need this trial and error method.
