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)
