Question

2x² + 20x + 50 = 0
2y² + 22y + 56 = 0

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

E. X = Y or relation cannot be established
Explanation:
2x² + 20x + 50 = 0
x² + 10x + 25 = 0
x = -5
2y² + 22y + 56 = 0
y = -4, -7

E. X = Y or relation cannot be established
Explanation:
2x² + 20x + 50 = 0
x² + 10x + 25 = 0
x = -5
2y² + 22y + 56 = 0
y = -4, -7
