Bhai mera bhi 2 hi aaya tha.
Answer given is \infty sec
Bro answer is wrong. How can 3*(infinite)^2-infinite^3 be +ve?
Another question with similar question but diff eqn has also infinite as answer!!
Wait for @Siddhant_Mudholkar
At +inf it wud tend to -inf so max positive value imo Shud be 2 sec only.
It should be 2t^2+t^3 for infinity. Maybe answer is misprinted or question is misprinted
