Quadratic Inequalities
Find the roots
1. x^2 + 2x + 1 <= 0
2. x^2 - 6x + 9 >= 0
~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

1.   = .

    The only solution of the inequality   <=   is the point x = -1, where the polynomial is equal to 0.

2.   = .

    The solution of the inequality   >=   is the entire number line (all real numbers).
