#### Answer:

#### Explanation:

The polynomial has 4 roots:3,4,5 and 6.

Each term will be negative if x<root

equal to zero if x=root

Bigger than zero if x>root

A table of + and - would be almost impossible to do here, so let's make a list:

if x<3: all terms are negative so the multiplication gives negative

if x=3 polynomial equal to 0

if x in ]3,4[, (x-3) is positive and (x-4) (x-5) are negative, so the multiplication will give positive

if x=4 polynomial equal to 0

if x in ]4,5[, only (x-5) is negative so the multiplication will give negative

if x=5 polynomial is undefined

if x in ]5,+oo[, all terms are positive so multiplication will give positive

(x−6)^2 will always positive except when x=6.

The result is
