Solving Derivatives: Find f'(x) of 6/(z^2+z-1)

[rtran58]

Homework Statement

Find the Derivative of

f(x) = [tex]\frac{6}{z^{2}+z-1}[/tex]

Homework Equations

The Attempt at a Solution

[tex]6\left(z^{2}+z-1\right)^{-1}[/tex]

Use Chain Rule to conclude

[tex]\frac{-12z - 6}{(z^{2}+z-1)^{2}}[/tex]

Is this right?

Yes that is correct.


btw that f(x) should be f(z)
