Quadratic Equations – Part 5

Type: Inequalities

When we got such cases like below in the given problem the answer is cannot be determined.

  • (-,-) and (+,-) 
  • (-,-) and (-,-)
  • (+,-) and (+,-)

Example 1: x^{2}+x-20 ; y^{2}-y-30 which is a greater value x or y from both equations?

It is matched with the first case so the answer is cannot be determined or relationship does not exist.

Example 2x^{2}+x-206y^{2}+y-1 which is a greater value x or y from both equations?

It is matched with the third case so the answer is cannot be determined or relationship does not exist.

Example 312x^{2}-2x-4 y^{2}-y-30

It is matched with the second case so the answer is cannot be determined or relationship does not exist.

Example 4: If you find  (-, +)  and (+,+) pair in the given problem the answer is (-,+)  >  (+,+)

Example: y^{2}+8y+15 x^{2}-8x+15

The answer is X>Y
