Qudratic equalities, inequalities with parameter

1. What kind of values of real parameter p have the two different real solutions of the following equation: (p-2)x^2 - (p-5)x + 1 = 0 2. Describe the values of real parameter m, so that all real numbers must be solutions of the following inequality: (m-1)x^2 + (2m+7)x + m-2 < 0
Control your solutions with this GeoGebtra applet. Remember, that GeoGebra helps you to - estimate the solutions of equalities, inequalities - understand the behavior of equalities, inequalities depends on parameter.
