Answer» Correct Answer - Option 1 : x ˃ y From equation I) we get, 4x2 + 13x + 9 = 0 ⇒ 4x2 + 4x +9x + 9 ⇒ 4x (x +1) +9(x + 1) ⇒ (x +1)(4x + 9) x = -1, -9/4 From equation II) we get, 4y2 + 20y + 25 =0 ⇒ 4y2 +10y +10Y +25 ⇒ 2y(2y + 5) + 5(2y + 5) ⇒ (2y + 5) (2y + 5) ∴ y = -5/2, -5/2 Comparison between x and y (via Tabulation):
∴ x > y |
