Question

What is the solution set of the quadratic inequality x^2-5-0?

Answer 1

Answer:

The solution set of the given quadratic equation is:

                       $x=\sqrt{5}\ and\ x=-\sqrt{5}$

Step-by-step explanation:

We are given a quadratic equation in terms of the variable ''x'' as:

                              $x^2-5=0$

Now we are asked to find the roots of this polynomial equation.

on adding both side of the equation with 5 we get,

$x^2-5+5=0+5\\\\x^2=5$

Now on taking the square root on both the side we get:

$x=\pm \sqrt{5}$

Hence, the roots are:

          $x=\sqrt{5}$ and $x=-\sqrt{5}$

Answer 2

To solve this, we just have to subtract the numbers.
$-5-0=-5$
$=x^2-5$
That's our solution set.

Have a nice day! :)
