Answer» Correct Answer - Option 3 : No relation or x = y I.x2 + 10x -24 = 0 ⇒ x2 +12x -2x - 24 =0 ⇒ x(x + 6) -2(x + 6) = 0 ⇒ (x + 6) (x - 2) = 0 ⇒ x = -6, 2 II. 3y2 - 12y - 15 = 0 ⇒ 3y2 - 15y + 3y - 15 =0 ⇒ 3y(y - 5) + 3(y - 3) = 0 ⇒ (3y + 5) (3y + 3) =0 ⇒ y = 5/3, -1 Comparison between x and y (via Tabulation):
∴ There is no relation between x and y
