I think I am completely lost. This last lesson we did and I just can't seem to grasp what to do.
Can someone explain this or am I a lost cause?
1) -x^2 + 4x + 5 >= 0
I am not sure where to begin to solve to graph this other than -(x+5)(x+1)
I guess I can use the test point method, but I do not fully understand that.
Rational inequality example:
2) (x^2 - 5x + 6) / (2x - 7) <= 0
If anyone can shed some light on the subject, I would greatly appreciated.
