Question
I. 5x² -14x + 8 = 0  II. 2y² + 17y + 36 =
0Â Â Â In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer.Solution
I. . 5x² -14 x + 8 = 0   5x² - 10x - 4x + 8 = 0   5x(x-2) - 4 (5x – 2) (x -2 ) (5x-4) x = 2, 4/5 II. 2y ²  - 17y  + 36 = 0     2y ² + 9y + 8y + 36 = 0   y (  y + 9) + 4( y  + 9) (y  + 4) (2y + 9) y = - 4, -9/2 Hence, x > y
