anyone knows what are the coditions for unique solution, infiitely many soutions and no solution for 2 quadratic equations? here is a conditio of coefficients that is to be satisfied?
In the Wimbledon Tennis tournament of 2014 players ranked 1 to 64 participated. In the first round, the first match was played between the top ranked i.e. 1st ranked and the lowest ranked i.e. 64th ranked players, the second match was played between 2nd ranked and 63rd ranked players and so on. In the next round, the winner of match 1 played against the winner of match 32, winner of match 2 played against the winner of match 31 and so on. This pattern continued in the subsequent rounds as well, till the final. When a lower ranked player beats a higher ranked player it's called an upset.
