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: $\displaystyle q(p+...)$
For #2, perhaps visually seeing the terms differently will help. You have: $\displaystyle \frac{12}{6}*{b^2}{b}*{a^2}{1}$
Same process for 3.
