The function changes sign at x = -6, 7 and -4.
It is positive only where all three terms are positive (x > 7) , or where one factor term is positive and two are negative (-6 < x < -4)
Put that into set terminology.
Help, Im stuck....
I cannot remember what to do.
(x+6)(x-7)(x+4)>0
The solution set is....{x, }
Thank you:)
