Homework Help: maths

Posted by Marian on Monday, February 7, 2011 at 11:57am.

I'm stuck here don't have a clue what to do. I've read all my school textbooks but it doesn't make much sense!! The numbers after the letters are small figures as in they u3 meaning( u x u x u). Ta!

Factorise the expression
5 u3v +15 uv2-10v
taking out the highest common factor. Choose the expression that remains in brackets when this is done.
Select one:
u 3 + 3 uv − 10 
u 3 + 3 uv − 2
u 3 + 15 uv − 2 
u 3 + 3 uv 2 − 2 
u 3v + 3 uv − 2 
5 u 3 + 3 uv − 2 
u 3v + 3 uv 2 − 2 v 
5 u 3 + 15 uv − 10
