X-25 (x-2) √√x²+2x Converges? Dieverges? dx AND WHY?

thank you for the explanation but i think you misunderstood me the exam is an mcq exam of 25 minutes i cannot spend 10 mins integrating this and the options that i gave you do not ask for alpha to be exactly -0.29 now your answer is correct but it is long there is a way to solve it to know that alpha converges to less than 0 without computing it as the exam is theory based and not computational would you know how to explain to me that it converges to less than 0 without the long computation by just using theories

can you explain how you got (x-2)=(t-3) and can you explain how you got the new limits because the question doesnt require all this complicated computation the question to be clear is a) converging to alpha less than 0. b) converging to alpha greater than 0. c) conveging to 0. d)diverging
