Which of the following equations is of a parabola with a vertex at (1, -2)?

Well idk what the following equations are because I don't see a picture, but if the answer choices are given to you in vertex form then it should look close to the squared answer in my picture. If the aren't given in vertex form, then you will have to give me the equations so I can show you how to convert to vertex form.

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.
