Given the expression (3s4)(4s+5), explain in words the steps taken to completely simplify the expression

My general advice to answer this type of question is to do what it says in the question, but make a simple note of each step that you do. Then write up the notes of the steps.
This question does not give guidance on the format required, so you could produce a simple list of steps?
