(4x-2)/2 * 3x/4 = ?? (Fractions)

(4x-2)/2 * 3x/4 = ?

Could someone give detailed instructions on how to get the answer?? I've tried so many sites, and everyone keeps being mean.
(Man, I sound pitiful.)
But seriously, I need some help.

Re: (4x-2)/2 * 3x/4 = ?? (Fractions)

Multiply the numerators together -> (4x - 2) * 3x. This requires the distributive property -> (4x)(3x) + (-2)(3x) = 12x^2 -6x = your numerator.
Multiply the denominators together -> 2*4 = 8. That's your denominator.
So you have (12x^2 - 6x) 8
You can simplify this in 2 different (but equally popular) ways.
