Question

(x-1)^2 * (x+2)^3 >= 0
helpppp please!

Answer 1

Well, the left side cannot be negative, (or zero)can it?

The first term can never be negative, but the second can if x<-2

So as long as x is >-2, the statement is true.

Answer 2

oops, the statement includes zero as being allowed, so x>=-2
