If:

f(x)= -460+100Q-Q^2

Then:

f´(x)=df/dQ=100Q+2Q=2*(50+q)

For Q=10

f´(x)=2*(50+10)=2*60=120

f(Q)= -460+100Q-Q^2

not f(x)

and

f´(Q)=df/dQ=100Q+2Q=2*(50+q)

f´(Q)=2*(50+10)=2*60=120

In google type: calc101

When you see list of results click on:

Calc101com Automatic Calculus,Linear Algebra and Polynomials

When page be open clik option: derivatives

When this page be open in rectacangle type:

-460+100Q-Q^2

In rectacangle with respect to:

type Q

in rectacangleand again with respect to: type Q

and click options DO IT

You will see solution step-by-step

By the way on this site you can practice any kind of derivation.
