Question
I. 63x2 + 148x + 77 = 0 II. 21y2
+ 89y + 88 = 0 In the following questions, two equations numbered I and II are given. You have to solve both questions and give answer among the following options.Solution
I. 63x2 + 148x + 77 = 0 63x2 + 49x + 99x + 77 = 0 7x(9x + 7) + 11(9x + 7) = 0 (7x + 11)(9x + 7)= 0 x = -11/7, -7/9 II. 21y2 + 89y + 88 = 0 21y2 + 56y + 33y + 88 = 0 7y( 3y + 8) + 11(3y + 8) = 0 (7y + 11) (3y + 8) = 0 y = -11/7 , - 8/3 So x ≥ y
