Question
I. 6x² + 37x + 45 = 0 II. 3y² - 11y + 6 =
0 In the following questions, two equations numbered I and II are given. You have to solve both the equations and find out the correct option. Give answer if ;Solution
I. 6x² + 37x + 45 = 0 6x² + 10x  + 27x + 45 = 0 2 x (3 x + 5) + 9 (3 x + 5) = 0 (2 x + 9) (3 x + 5) = 0 ∴ x = -9/2, -5/3 II. 3y² - 11y + 6 = 0 3y² - 2y - 9 y + 6 = 0 y (3 y – 2) – 3(3 y – 2) = 0 (y – 3) (3 y – 2) = 0 ∴ y = 3, 2/3 Hence, x < y.
