I would like some help on differentiating the lorentz factor with respect to time

2. Relevant equations

3. The attempt at a solution

i arrived at [tex] (-1/2) (1-v^2/c^2)^{-3/2} [/tex]

but a forum on this website says it is [tex] (-1/2) (1-v^2/c^2)^{-3/2} ( \frac{-2v}{c^2} dv/dt)[/tex]

Please help!
