[SOLVED] need some help simplifying :)
ok I was wondering if anyone could tell me what these equations are simplified

1) pq + 3qr - 2rq +6qp

2) (12a²b²)/6b

3) 6mn * (-2m²n³)

I would really appreciate any help

For #1, what's your common term. It's "q". So factor that out and see what you've got left, just like so: $q(p+...)$

For #2, perhaps visually seeing the terms differently will help. You have: $\frac{12}{6}*{b^2}{b}*{a^2}{1}$

Same process for 3.
