p:c^2>； You can introduce: c

q:x^2+4cx+ 1>； 0 is a discriminant

Because p or q is true, p and q are false.

So p and q are true or false.

When p is true: c

When q is true:-1/2

Up: (negative infinity,-1/2 or 0, 1/2) or (1, positive infinity)

2:

p:-b/2a & lt； 0 and discriminant >; 0, it can be deduced that: m>2

Q: Discriminant formula

Because p or q is true, p and q are false.

So p and q are true or false.

As mentioned above: (0, 2 or 4, positive infinity)
