This is taking me more than an hour to simplify and I think I did it wrong. Also can someone give me tips on how to simplify without getting it too messy?

10(2x + 1)^4(x^3 - x + 1)^4 + 4(2x + 1)^3(x^3 - x + 1)^3(3x^2 - 1)

can a mod move this to the urgent homework help forum please

It's not hard. Note that $\displaystyle 2x+1$ and $\displaystyle x^3-x+1$ are common factors, so all you need to do it is to factorise that expression.

Eh I tried and I got a mess and now I'm confused...this is where I am right now

(2x + 1)^3(x^3 - x + 1)^3(10(2x +1)(x^3 - x + 1) + 4(3x^2 - 1))

(2x + 1)^3(x^3 - x + 1)^3(10(2x +1)(x^3 - x + 1) + 4(3x^2 - 1))
anyone =(

5. as i can see, you have simplified the expression correctly.
