Problem 2-10: Diffrentiating


Diffrentiate
a)  f_1\left(x\right)= \displaystyle\frac{1-2x^2}{1+x+x^2}
b)  f_2\left(x\right)= (1-2x^2)(1+x+x^2)

Solution
The following rules can be used:
I)  \displaystyle\frac{d}{dx}ax^n=anx^{n-1}
II)  \displaystyle\frac{d}{dx}\left(u+v\right)=\frac{du}{dx}+\frac{dv}{dx}
