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. 6x² - 49x + 99 = 0 6x² - 27x - 22x + 99 = 0 3x(2x – 9) - 11 (2x – 9) = 0 (3x – 11) (2x – 9) = 0 x = 11/3 , 9/2 II. 5y² + 17y + 14 = 0 5y² + 10y + 7y + 14 = 0 5y(y + 2) + 7(y + 2) = 0 (5y + 7) (y + 2) = 0 y = - 2, 7/5 Hence x > y.
