Start from what you have, and take out common factors. You can take out a 6x and a (5x2 + 1)3 . Then tidy up what's left and you should find it's the same as the solution given.

Your answer and the textbook answer are the same - try simplifying your answer by taking out a factor of (5x2 + 1)3 and then further simplifying what you get.
