x≤−9 or x≥5 or x=0

Step-by-step explanation:

Let's solve your inequality step-by-step.

x2(x+9)(x−5)≥0

x4+4x3−45x2≥0

Let's find the critical points of the inequality.

x4+4x3−45x2=0

x2(x−5)(x+9)=0(Factor left side of equation)

x2=0 or x−5=0 or x+9=0(Set factors equal to 0)

x=0 or x=5 or x=−9

Check intervals in between critical points. (Test values in the intervals to see if they work.)

x≤−9(Works in original inequality)

−9≤x≤0(Doesn't work in original inequality)

0≤x≤5(Doesn't work in original inequality)

x≥5(Works in original inequality)

x≤−9 or x≥5 or x=0
