the main idea is to get the derivative of denominator in the numerator
derivative of 2x^2 is 4x,so multiply and divide by 2 and take 2 common from numerator and then take 2x^2+18=t and you will get the answer as 2log(2x^2+18) which is same as the answer earlier posted.
you can differentiate and check!!
