Same old parenthesis-free exposition. Surely by now you can factor the expressions and eliminate common factors.
Take a look at
http://www.wolframalpha.com/input/?i=%28%283h^3+-+6h%29%2F%2810g^2%29%29+*+%28%284g%29%2F%28g^2+-+2g%29+%29
and notice how the parentheses make things work.
wolframalpha.com is your friend. It can solve these problems, and has the added benefit of forcing you to correctly express you fractions.
Multiply. Simplify your answer.
1. (3h^3 - 6h/10g^2) x (4g/g^2 - 2g)
(This is the correct expression. There is no typo.)
A: ?
2. (m^2 + m - 2/m^2 - 2m - 8) x (m^2 -8 + 16/3m -3)
(This the correct expression. There is no typo.)
A: ?
