Answer 1

Heya folk....
:
For any quadratic equation, to find the vertex of parabola we use the formula
.... h = –b/2a....!!
:
Hope this helps...!!!

Answer 2

(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.
