Algebra II AGAIN. ugh. :/?

Question

okay im starting to get this. i havent taken math in over a year :/ so this ones kinda hard

2(m - n squared) - 6(n squared + 3m)

thanks guys youre a big help ;)

Answer 1

-8n^2-16m

Answer 2

First thing to do is clear the parentheses.

2m - 2n^2 - 6n^2 - 18m

Next collect like terms.  That is, the n^2 terms, the n terms and the m terms.

2m - 18m - 2n^2 - 6n^2

-16m - 8n^2

That's about it.  Unless you want the higher order term (squared term) first:

-8n^2 - 16m

Answer 3

-8nsquared - 16 m

which = nsquared + 2m I believe
