I posted an interesting question on Integration here.
Allow me to repeat. There isn’t any product rule nor quotient rule in Integration.
So to Integrate the question, some "extra" work must be done to "dissolve" the product nature of the question.
These are the steps that must be taken even before Integration beings:
- Factorise the terms inside the Square Root
- Combine common term (2x+1) by applying Indices Law
- Remember to + c as this is a indefinite integral aka no limits given
