Question
I. 8x² - 74x + 165 = 0 II. 15y² - 38y + 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. 8x² - 74x + 165 = 0 8x² - 30x - 44 x + 165 = 0 2 x (4 x – 15) – 11 (4 x – 15) = 0 (2 x – 11) (4 x – 15) = 0 x = 11/2, 15/4 II. 15y² - 38y + 24 = 0 15y² - 18y - 20 y + 24 = 0 3 y(5 y – 6) – 4(5 y – 6) = 0 (3 y – 4) (5 y – 6) = 0 y = 4/3, 6/5 Hence, x>y
