Quadratic Inequalities 

Find the roots

1. x^2 + 2x + 1 <= 0

2. x^2 - 6x + 9 >= 0
~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
1.  {{{x^2 + 2x + 1}}} = {{{(x+1)^2}}}.

    The only solution of the inequality  {{{x^2 + 2x + 1}}} <= {{{0}}}  is the point x = -1, where the polynomial is equal to 0.
</pre><pre>
2.  {{{x^2 - 6x + 9}}} = {{{(x-3)^2}}}.

    The solution of the inequality  {{{x^2 - 6x + 9}}} >= {{{0}}}  is the entire number line (all real numbers).
