x = t { (t-1) (t-2) }
x = t { t2 - 3t + 2 }
x = t3 + 3t2 - 2t
Given v = 0 
 \frac{\mathrm{d} x}{\mathrm{d} t}=0
\frac{\mathrm{d} (t^{3}-3t^{2}+2t)}{\mathrm{d} t}=0
                3t2 - 6t + 2 = 0
Solving you get      
t = \frac{1 - (3)^{\frac{1}{2}}}{3^{\frac{1}{2}}} 
        and         t = \frac{- (3)^{\frac{1}{2}-1}}{3^{\frac{1}{2}}}
Substitute this in x,
you will get x. try doing it that way, I hope you could get the answer. I’m not good in algebra to solve further. 
To find acceleration,
a = \frac{\partial^2 x}{\partial t^2}
 
    = d2 (t3 - 3t2 + 2t)/dt2
     = 6t - 6

Substitute t in the question. Hope this was helpful. It is very difficult to do all the algebraic solution for me. This answer is not complete I know it. But this the fartest explaination I can give, if you have any doubt in this explaination ask me in this page itself if you open it as a new query it would be difficult for me to locate you. As the doubt by entering it as an answer in the same page.
