Factor out the greatest common denominator (GCF) from each group.

Factor the polynomial by factoring out the greatest common factor, 
(x+y)(x-2)
a. Practically speaking, you compute the differential in much the same way you compute a derivative via implicit differentiation, but you omit the variable with respect to which you are differentiating.

Aside: Compare this to what happens when you differentiate both sides with respect to some other independent parameter, say
:

b. This is just a matter of plugging in
and
.

You divide 326/344 and multiply by 100. 94.78%
