Question

solve inequality -x2(x+3)<0

Answer 1

Answer:

-x²(x+3)<0

or, x²(x+3)>0

or,x²>0, (-3)

Answer 2

Answer:

x={3, +infinity} or x >3

Step-by-step explanation:

-x2(x-3) < 0

x2(x-3) > 0

x2>0 -> x=R -{0}

x-3>0 -> x > 3

x2<0 -> x=Emptyset

x-3<0 -> x<3

find intersections

x={3, +infinity} or x >3
