Quadratische Funktionen | Scheitelform und allgemeine Form | Satz vom Nullprodukt (einfach erklärt)

What is the vertex form and the general form of a quadratic function? How can you convert or transform one form into the other? You use the second binomial formula and multiply out to get the general form. The way back is more difficult: Using the mean of the zeros, you find the x-coordinate of the vertex. This allows you to calculate the y-coordinate. Since the dilation factor remains the same, you can now set up the vertex form. Do you have questions or feedback? Leave a comment!
