Homework Help: Math

Posted by Teresa on Sunday, January 28, 2007 at 1:06pm.

Factor Completely: I am really confused on how to start it.

12q^5w^2-36q^4w^3-120q^3w^4

Help please. :)

Factor out 12q^3w^2:

12q^3w^2(q^2 - 3qw - 10w^2)

Can we factor further? Yes.

q^2 - 3qw - 10w^2 factors are (q - 5w)(q + 2w).

We end up with this:

12q^3w^2(q - 5w)(q + 2w)

And that's as far as we can factor on this one!

I hope this will help.
