    Simplyfying help!

    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 2x+1 and x^3-x+1 are common factors, so all you need to do it is to factorise that expression.

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