Solve the inequality. write your answer using interval notation. x(x âˆ’ 3)(x + 4) > 0

AfilCa [17]

Sorry But I can't understand what Ă˘Ë†â€™ means so i will solve this for x+3 and x-3
first for x+3
equation e= x(x+3)(x+4)>0
so points are x= 0,-3,-4
for range x<-4
e<0
for -4<x<-3
e>0
for -3<x<0
e<0
and for x>0
e>0
so the interval when e>0
x â (-4<x<-3 and x>0)

now for x-3
equation e=x(x-3)(x+4)>0
so points are x= 0,3,-4
for range x<-4
e<0
for -4<x<0
e>0
for 0<x<3
e<0
and for x>3
e>0
so the interval when e>0
x â (-4<x<0 and x>3)
