The product rule seems to have used three parts of four in each equation so they are not seperable which is confusing for me.

Glad I found this. I am not great at solving expressions, I have a doubt why we need to do gradient for solving L, Is that the standard proc or anything else, Please someone clarify. Sorry if this is a silly one...

can you check your math? the differentiation in the last term doesn't look right to me. if u= w^T*X^T*X and v = w, using the product rule, you will get a different result.
