## anonymous 5 years ago factor the polynomial and check your answer 4m^4 - 2m^2 + 8m

Is there a common power of m in all three of those terms?

2. anonymous

nope

There is. Remember that $$m^4 = m \cdot m \cdot m \cdot m$$ and $$m^2 = m \cdot m$$.

4. anonymous

what?

$4m^4 - 2m^2 + 8m = 4mmmm - 2mm + 8m$ So you can pull a single m out of all three terms: $m(4m^3 - 2m + 8)$ There's one more common factor, it's a number though. Is there a factor common to 4, 2, and 8?

2?
