设命题P:实数x满足x2-4ax+3a2设命题P:实数x满足x2-4ax+3a2设命题P:实数x满足x2-4ax+3a2p:(x-a)(x-3a)q:(x+2)/(x+4)≥0,解得x≥-2或x若非P
设命题P:实数x满足x2-4ax+3a2
设命题P:实数x满足x2-4ax+3a2<0,其中a<0,命题q:实数x满足x+2/x+4≥0,且非P是非q的必要不充分条件,求a的取值范围.
设命题P:实数x满足x2-4ax+3a2
p:(x-a)(x-3a)<0,由于 a<0,解得 3a
若 非P是非q的必要不充分条件,则p是q的充分不必要条件,从而
{x|3a
即 a的取值范围是a≤-4 或 -2/3≤a<0
