Instructions

In these questions, two equations numbered I and II are given. You have to solve both the equations and mark the appropriate answer. Give answer

Question 58

I. $$x^{2}+11x+18=0$$
II. $$y^{2}-\sqrt{81}=0$$

Solution

I : $$x^{2} + 11x + 18 = 0$$

=> $$x^{2} + 2x + 9x = 18 = 0$$

=> $$x (x + 2) + 9 (x + 2) = 0$$

=> $$x$$ = -2, -9

II : $$y^{2} - \sqrt{81} = 0$$

=> $$y^{2} = \sqrt{81}$$

=> $$y^{2} = 9$$

=> $$y$$ = 3, -3

Since, 3 > -2 > -3

Hence, no relation can be established.
