Difficulty: Easy
Correct Answer: If x > y
Explanation:
Introduction / Context:
The second relation was typographically unclear. Using Recovery-First Policy, we interpret √225 y + 2 = 0 as (√225)·y + 2 = 0 ⇒ 15y + 2 = 0. We then solve both and compare the numeric values using the greater real root convention for the quadratic.
Given Data / Assumptions:
Concept / Approach:
Solve each: isolate x^2 and y. For comparison, evaluate numerically and select the correct inequality.
Step-by-Step Solution:
Verification / Alternative check:
Decimal check: x ≈ 0.133…, y ≈ −0.133…, confirms the inequality.
Why Other Options Are Wrong:
They reverse the sign relation or claim equality, which is false given the computed values.
Common Pitfalls:
Misreading √225 y as √(225y); the intended linear form is (√225)·y.
Final Answer:
If x > y
