I. x^2 + 14x + 49 = 0 \rightarrow x = -7 II. y^2 + 9y = 0 \rightarrow y = 0, -9 What is the relation between x and y?

1. x < y
2. x > y
3. No relation
4. x \ge y

Correct answer: No relation

Solution

From the first equation, x = -7. From the second equation, y can be 0 or -9. If y = 0, then x < y; if y = -9, then x > y. Since the relation changes, no definite relation exists.
