Two quadratic equations (I) and (II). Find relation between x and y.

1. if x > y
2. if x ≥ y
3. if x < y
4. if x = y or relation cannot be established.

Correct answer: if x = y or relation cannot be established.

Solution

After solving both quadratic equations and comparing all (x,y) pairs, the comparison yields x=y in some cases and no consistent relation otherwise. Hence the relation cannot be established.
