Question
I. 10x² - 11x + 3 = 0 II. 42y² - 23y
– 10 = 0 In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer.Solution
I. 10x² - 11x + 3 = 0 10x² - 6 x - 5 x + 3 = 0 2 x (5 x - 3) – 1(5 x - 3) = 0 (2 x – 1)(5 x - 3) = 0 ∴ x = 1/2, 3/5 II. 42y² - 23y – 10 = 0 42y² - 35y + 12 y – 10 = 0 7 y(6 y – 5) + 2(6 y – 5) = 0 (7 y + 2)(6 y – 5) = 0 ∴ y = -2/7, 5/6 Hence, relationship cannot be established between x and y
