Question 479020
Find the sign of the following expression: -(c-b)^3(a-c)^2
---
-(c-b)^3 is negative if c>b
---
-(c-b)^3 is positive if c<b
-----
(a-c)^2 is always positve as long as a is not equal to c.
-----
So your product is negative if c>b
And you product is positive if c<b
And it is zero if a = c
