Two Math Problems of Senior Two on Proposition
1 is a true proposition, and set A is a subset of set A ∪ B. 。

Proposition p: equation a? x? +ax-2=0 has a solution on [- 1, 1].

Equation (ax+ 1/2)? = 2+ 1/4->; Solution: x 1 = 1/a, x2 =-2/a.

If p is a true proposition,-1

If p is a false proposition,-1

Q: Only one real number X satisfies the inequality X? +2ax+2a≤0

x? +2ax+2a=0 Only equiroots, x? +2ax+2a=(x+a)? -a? +2a

-a? +2a = 0->; A=0 or a=2

That is, when a=0 or a=2, the proposition q is true.

If q is a false proposition, a! =0 and a! =2

If the proposition "p or q" is false,->; Answer! =2,

...........................

If the propositions "p and q" are true propositions, a=2.

...................

If the propositions "p and q" are false propositions,->; ,- 1 & lt; a & lt0,0 & lt; a & lt 1
