Solve I. $x^{2} - 16 x + 64 = 0$
II. $y^{2} - 18 y + 80 = 0$ , 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 = 8

(a repeated root);

y = 8

or 10. So

x

is never more than

y

, and they can be equal:

x

≤

y

.

Answer: A)

x

≤

y
