The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.

There are several ways that can help someone recover after they are injured. After the injury occurs, it is best to go to the doctor or hospital to get the injury, if need be, checked on or fixed. Another thing that can help is if the person rests and does not do any heavy-lifting or do to many activities that can strain the injury. After an injury occurs, if you do not rest there is more of a likelihood that you can damage it more and also rest helps the body heal. There are also several medicine's that are meant to help relieve pain after an injury occurs.
