Question

find the derivative of (√x-3x)(x+1/x) .... [the answer is 3/2√x-6x-1/2x√x]...I want the right solution with steps​

Answer 1

Answer:

f(x)= (√x - 3x) (x + 1/x)

Step-by-step explanation:

First derivative:

d/dx[f(x)] = f' x=

(1/2√x-3) (x+1/x) + (1- 1/x^2) (√x-3x)

Simplify/ Rewrite:

-(12√x-3) x^3 + x/2x^5/2
