Answer» Correct Answer - Option 5 : x = y or relationship between x and y cannot be established. Given∶ I. x2 - 13x + 40 = 0 ⇒ x2 - 8x - 5x + 40 = 0 ⇒ x(x - 8) - 5 (x - 8) = 0 ⇒ (x - 5) (x - 8) = 0 ⇒ x = 5, 8 II. y2 - 15y + 54 = 0 ⇒ y2 - 9y - 6y + 54 = 0 ⇒ y(y - 9) - 6 (y - 9) = 0 ⇒ (y - 6) (y - 9) = 0 ⇒ y = 6, 9 Comparison between x and y (via Tabulation):
Hence, Relation between x and y is not established. |
