So for example with PCL3, would you just subract one O's value from P, or 3 O's? It isn't explained in my textbook.

i.e. 3(3.5)-2.1 or 3.5-2.1?

Also, how do you figure partial charge?

ok this is another quadratic thing...
x^2+y^2=2
y=x-2
so far this is what i got
x^2(x-2)(x-2)=2 x^2+x^2-2x-2x+4=2 2x^2-4x+4=2
-2 -2
2x^2-4x+2=0
any ideas?
