Question 430837
.
x^2 + 8x + 15 >= 0
~~~~~~~~~~~~~~~~~~~~~~~~~



        The solution and the answer in the post by @mananth both are incorrect.

        I came to bring a correct solution.



<pre>
This request is to solve inequality

    x^2 + 8x + 15 >= 0.


Left side can be factored

    (x+5)*(x+3) >= 0.


The solution for this inequality is the union of two sets of real numbers

    x <= -5  OR  x >= -3.


In the interval form, the solution is  ({{{-infinity}}},{{{-5}}}] U [{{{-3}}},{{{infinity}}}).
</pre>

Solved correctly.
