Find the roots and decide the relation: I. $x^{2} - 17 x + 72 = 0$
II. $y^{2} - 9 y + 14 = 0$ .

Competition practiceQuadratic Comparison

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

Step-by-Step Solution

I gives

x = 8

or 9. II gives

y = 2

or 7. Every

x

is larger than every

y

, so

x > y

.

Answer: D)

x > y
