"Numerical factors in this term have been multiplied." is deeply insufficient to explain how you got from the previous step to the following one. I am totally lost. I need to "show my work" and you've not shown me how to do the work, so I can't do it. Please show the process/notation for all the steps, it's what I paid for.
