Question

I have given 2 answers to the above question, 1 from the solutions from the book and the other from my personal calculation. As you can see the answers are different because in the solutions manual the limits of integration are between -1 and 1 while in my calculation they are between 0 to 2.I want someone to tell me if my method is wrong, as the question doesnt specify the limits of integration and if it is wrong then why. please give a detailed explanation and answer in the form of an uploaded image as I do not understand the computer notation. A satisfactory answer will be rewarded with points immediately.thanks.
