II. $y^{2} + 21 y + 110 = 0$ , then choose the relation between $x$ and $y$ .

Competition practiceQuadratic Comparison

A $x > y$
B $x$ ≥ $y$
C $x < y$
D $x$ ≤ $y$

Step-by-Step Solution

x = - 9

or −10;

y = - 10

or −11. Every

x

is greater than or equal to every

y

(−10 = −10 is possible), so

x

≥

y

.

Answer: B)

x

≥

y
