Question

(x + 2)(x + 1) = (x – 2)(x – 3), (y + 3)(y + 29) = 360

  • 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:
(x + 2)(x + 1) = (x – 2)(x – 3)
x = 1/2 = 0.5
(y + 3)(y + 29) = 360
y = 7, -39

E. X = Y or relation cannot be established
Explanation:
(x + 2)(x + 1) = (x – 2)(x – 3)
x = 1/2 = 0.5
(y + 3)(y + 29) = 360
y = 7, -39
