-5 < x - 4 greater than it equal 1

We have expression that renders the system of inequalities,

Which can be simplified to,

So what we get is something greater than -1 and at the same time greater or equal to 5, so the solution is,

.

Hope this helps.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
