Answer: -8(5x^4-2)

Step-by-step explanation:

The greatest common factor of 16 and -40 is -8.

Answer:

- 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)
