Finding Vertex in Factored form
I learned this week in Pre Calc 11 is how to find the vertex of a quadratic equation that is in factored form. The first step is to find the x-intercepts or “zeros” of the equation. Once you’ve determined the zeros/ x-intercepts, you find the average of the zeros by adding them and dividing them by two. Once you find that, you plug it in as X in the equation in order to find Y. The x and y coordinates are the coordinates to your vertex.
This can help you if above is not detailed enough
