2.

$\displaystyle \frac{x^2 - 5x + 4}{2x - 8}*\frac{1}{3x^2 - 3x} =

\frac{(x - 4)*(x - 1)}{2(x - 4)}*\frac{1}{3x(x - 1)} =

$...

(Ok, I'm LaTex impaired. Can anyone edit this?!?!)

Can you take it from here? - Mar 7th 2011, 07:20 PMWilmer
1: 7g / y^2 / 21g^3

= 7g / (21g^3 y^2)

= 1 / (3g^2 y^2)
