This is a repeat question. (x2)

x^2 - 5x >= -6
x^2 - 5x + 6 >= 0
(x - 2)(x - 3) >= 0
x is in (-infinity, 2] and [3, infinity)
0........1........2........3........4........5

The solutions by   @CubeyThePenguin is INCORRECT.

I came to bring you the correct solution.

x^2 - 5x >= -6 -----------> x^2 - 5x + 6 >= 0 (x-3*(x-2) >= 0 ANSWER. The solution set is (-oo,2] U [3,oo).

Ignore the post by @Penguine, since his plot is incorrect.
