D( p )
6*p-(2*p^2) = 0
6*p-(2*p^2) = 0
6*p-(2*p^2) = 0
6*p-2*p^2 = 0
6*p-2*p^2 = 0
DELTA = 6^2-(-2*0*4)
DELTA = 36
DELTA > 0
p = (36^(1/2)-6)/(-2*2) or p = (-36^(1/2)-6)/(-2*2)
p = 0 or p = 3
p in (-oo:0) U (0:3) U (3:+oo)
(2*p)/(6*p-(2*p^2)) = 0
(2*p)/(6*p-2*p^2) = 0
6*p-2*p^2 = 0
2*p*(3-p) = 0
3-p = 0 // - 3
-p = -3 // * -1
p = 3
2*p*(p-3) = 0
(2*p)/(2*p*(p-3)) = 0
2*p = 0 // : 2
p = 0
p in { 0}
p belongs to the empty set
