Thread: Some simplification help please

I want to simplify:

(3x^2 +2) (x^2 +3) - (x^3 +2x+1)2x

According to my textbook, I should be arriving at:


x^4 + 7x^2 - 2x + 6

I'm getting a little stuck here! help would be kindly appreciated.

Expand everything:

I just needed it broken down as you kindly did - very straightforward now.

Thankyou !
