function with ln and log

I am having issues with plotting.

my function is

y2 = (x-1)(ln((3^.5)/2)*x-ln(3/8));

is not running because of ln but I have changed to log. still an error of some operator.

x range of [1, 3]

y2 = (x-1)(log((3^.5)/2)*x-log(3/8));
plot(x,y2)

Thanks.

It is missing a multiplication operator:

y2 = (x-1)(log((3^.5)/2)*x-log(3/8));
         ↑

Try this:

y2 = (x-1).*(log((3^.5)/2).*x-log(3/8));

This also uses element-wise operations. See Array vs. Matrix Operations for an extended discussion.
