Find the derivative of the following functions (it is to be understood that a, b, c, d, p, q, r and s are fixed non-zero constants and m and n are integers):

$$\dfrac{ax+b}{px^2+qx+r}$$

Asked by Pragya Singh | 1 year ago |  54

##### Solution :-

Let f(x)  $$\dfrac{ax+b}{px^2+qx+r}$$

By quotient rule,

$$\dfrac{(px^2+qx+r)(a)-(ax+b)(2px+q)}{(px^2+qx+r)^2}$$

$$\dfrac{(apx^2+aqx+ar-aqx+2npx+bq)}{(px^2+qx+r)^2}$$

$$\dfrac{-apx^2+2bpx+ar-bq}{(px^2+qx+r)^2}$$
