    distribute the negative in front of the ( )'s which changes all the signs within ( )'s:

    -5x^4 + x^2 - x^3 - 8x^2 + x

    combine like terms (same exponents):

    - 5x^4 - x^3 - 7x^2 + x

    that's it! ;)

    First, multiply the negative through. Then you have

    -5x^4 + x^2 - x^3 - 8x^2 + x

    Then combine the terms that are alike.

    -5x^4 - x^3 -7x^2 - x)

    That's it.

    - 5x^4 + x^2 - x^3 - 8x^2 + x (The signs in the second bracket change becuse of the minus sign in front of it.

    - 5x^4 - x^3 - 7x^2 + x
