Answer:
v = 0, 1, a
Explanation:
dv/dt = v(v² - (1 + a)v + a)
When dv/dt = 0
=> 0 = v(v² - (1 + a)v + a)
=> v = 0 and (v² - (1 + a)v + a) = 0
Open up the bracket:
v² - v - av + a = 0
v(v - 1) - a(v - 1) = 0
(v - a) (v - 1) = 0
=> v = a and v = 1
Hence, the values of v for which dv/dt can be 0 are v = 0, 1, a.
