Equations And Inequations Ques 93
I. $x^{2}=25$
II. $y^{2}+10 y+25=0$
Directions: In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer
(1) if $x>y$
(2) if $x \geq y$
(3) if $x<y$
(4) if $x \leq y$
(5) if $x=y$ or the relationship between $x$ and $y$ is not determinable.
Show Answer
Correct Answer: 93.(5)
Solution: (5) I. $x^{2}=25$
$\Rightarrow x=\sqrt{25}= 5$
II. $y^{2}+10 y+25=0$
$\Rightarrow(x+5)^{2}=0$
$\Rightarrow x+5=0$
$\Rightarrow x=-5$
