I think you wrote that it was divided by x^2 which is the same as multiplying by x^-2 so you can use the product rule rather than the quotieint rule which I think is eaisier.

and why do you use product rule instead of quotient rule? becasue g(x)= f(x)/x^2
OpenStudy (anonymous):
ah ok
thanks

i am just wondering why is that different from my answer using quotient rule
OpenStudy (anonymous):
sorry, i made mistake, its 1 as well :) sorry...
OpenStudy (anonymous):
well it should be the same.
g'(x)=(f'(x)*x^2-f(x)2x)/x^4
=(3*1-1*2*1)/1
=1
