Jeez that hurts.

6. bthemesandtricks

When I derived mine, I didn't know of Cramer's rule then I was still in the early period of high school. But Cramer used Matrices to derive his. I used another method. lol

@bthemesandtricks Don't give up. You discovery was a first for you. So, keep thinking.

8. bthemesandtricks

Besides its not the same formular just like the general method for solving quadratic equations and the completing the square method are similar so is my formula and Cramer's.
