factor the following expression 15 u v w^8+30 u^5 w^9 and factor 36 x^2-y^2 and 7u+7v+v w +wu
15uvw^8 + 30u^5w^9
First you find the GCF.
Can you do that with the hints I gave you in the previous question?
15uw is what I think. do you agree?
Once you have the GCF. You divide both parts by it
(15uw)(vw^7 + 2u^4w^8)
Can you do the other two? I will be happy to check your work.
