D( y )
y = 0
y = 0
y = 0
y in (-oo:0) U (0:+oo)
17/y = y // - y
17/y-y = 0
17*y^-1-1*y^1 = 0
(17*y^0-1*y^2)/(y^1) = 0 // * y^2
y^1*(17*y^0-1*y^2) = 0
y^1
17-y^2 = 0
17-y^2 = 0
DELTA = 0^2-(-1*4*17)
DELTA = 68
DELTA > 0
y = (68^(1/2)+0)/(-1*2) or y = (0-68^(1/2))/(-1*2)
y = -17^(1/2) or y = 17^(1/2)
y in { -17^(1/2), 17^(1/2)}
y in { -17^(1/2), 17^(1/2) }
