Question 237858: Okay, so what is a eauation for a line of symmetry for (x-2)(x-2)
also what are you equations for parabolas, with (2,0) as a vertex.
anyways i dont want you tto tell me the anwer i wannt to know how to answer, so it will help me
thanks :D

I think you want the equation for the line of symmetry for



Multiply the two binomials using FOIL.




Now you have your equation in Standard Form, namely



The vertex of any such parabola is at the point



Since the line of symmetry is a vertical line through the vertex, the equation of the line of symmetry must be:



===============================================================

The set of parabolas with vertex at is described by using the vertex form of the equation of a parabola.

The vertex form of a parabola with vertex at the point is:



So your family of parabolas is:
