Find the coefficient of y^4 in the expansion of (2y-5+3y^2)^6.  

 

That's too much multiplication to try to do it manually.  

 

So, I used a handy tool that has been put at our disposal,  

 

i.e, https://www.symbolab.com/solver/expand-calculator    

 

I found that the coefficient is 375. Go to there and see for yourself.
