Be careful and make multiplication explicit.
Instead of
de = diff(x, t) == 2 * x(15 - x)
you want
de = diff(x, t) == 2 * x * (15 - x)

Be careful and make multiplication explicit.
Instead The differential equation studied here is
$$
x'(t) = 2 · x(t) · (15 - x(t))
$$
and not
$$
x'(t) = 2 · x(15 - x(t))
$$
so instead of
de = diff(x, t) == 2 * x(15 - x)
you want
de = diff(x, t) == 2 * x * (15 - x)
