Answer» Correct Answer - Option 3 : x ≥ y Calculation: l. 24x2 + 38x + 15 = 0 ⇒ 24x2 + 18x + 20x + 15 = 0 ⇒ 6x(4x + 3) + 5(4x + 3) = 0 ⇒ (6x + 5) (4x + 3) = 0 ⇒ x = -5/6, -3/4 ll. 54y2 + 123y + 65 = 0 ⇒ 54y2 + 78y + 45y + 65 = 0 ⇒ 6y(9y + 13) + 5(9y + 13) = 0 ⇒ (6y + 5) (9y + 13) = 0 ⇒ y = -5/6, -13/9 Comparison between x and y (via Tabulation):
∴ The result will be x ≥ y. |
