Question
I. 22x² - 97x + 105 = 0 II. 35y² - 61y + 24 =
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. 22x² - 97x + 105 = 0 22x² - 55x - 42 x + 105 = 0 11 x(2 x – 5) – 21(2 x – 5) = 0 (11 x – 21) (2 x – 5) = 0 x = 21/11, 5/2 II. 35y² - 61y + 24 = 0 35y² - 40y - 21 y + 24 = 0 5 y (7 y – 8) – 3(7y – 8) = 0 (5 y – 3) (7 y – 8) = 0 y = 3/5, 8/7 Hence x > y.
(I) 10x2 - 7x + 1 = 0 (II) 35y2 - 12y + 1 =0
