Question

x² – 18x + 72 = 0
y² + 30y + 221 = 0

  • A) X > Y
  • B) X < Y
  • C) X ≥ Y
  • D) X ≤ Y
  • E) X = Y or relation cannot be established
Solution

A. X > Y
Explanation:
x² – 18x + 72 = 0
x = 12, 6
(y + 13) (y + 17) = 0
y = – 13, – 17

A. X > Y
Explanation:
x² – 18x + 72 = 0
x = 12, 6
(y + 13) (y + 17) = 0
y = – 13, – 17
