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: $\displaystyle (3x^4 + 9x^2 + 2x^2 + 6) - (2x^4 + 4x^2 + 2x)$ $\displaystyle = (3x^4 + 11x^2 + 6) - (2x^4 + 4x^2 + 2x)$ $\displaystyle = x^4 + 7x^2 - 2x + 6$
I just needed it broken down as you kindly did - very straightforward now. Thankyou !
