    - 8 (5x^4 - 2)

    Step-by-step explanation:

    Both can be simplified by 8.

    16 - 40 x^4 (8·2) - (8·5) x^4

    Subtract the 2nd half of the equation to place it in the front. There becomes an addition sign in the front of (8·2) because 8 is positive, but 8 is still negative.

    (8·2) - (8·5) x^4 - (8·5) x^4 + (-8·2)

    Then you'll factor out the only common number {-8} and then place the rest of the equation together. It remains a negative 8 because negative is more powerful than positive when they are factored together.

    - (8 ·5) x^4 + (-8·2) - 8 (5x^4 - 2)
