Difficulty: Medium
Correct Answer: x < y
Explanation:
Introduction / Context:
We compare solutions from two quadratic relations. If every possible x is strictly less than every possible y, we can conclude x < y. Compute the roots for both to compare their ranges.
Given Data / Assumptions:
Concept / Approach:
Use quadratic formula to get all roots. Compare the largest x to the smallest y; if the largest x is still less than the smallest y, then every x is less than every y.
Step-by-Step Solution:
Verification / Alternative check:
Check all pairings: {−3, 0.17647} versus {0.46154, 2}; all comparisons show x < y.
Why Other Options Are Wrong:
Common Pitfalls:
Not identifying the smallest y and largest x correctly; mixing signs or miscomputing discriminants can flip conclusions.
