Question

If y = x ^ 2 + x - 1/x * f * i * n * d * (dy)/(dx)​

Answer 1

Step-by-step explanation:

$y = {x}^{2} + x - \frac{1}{x}$

$Then, \frac{dy}{dx} = \frac{d}{dx} y =$

$\frac{d}{dx} ( {x}^{2} + x - \frac{1}{x} )$

$\frac{d}{dx} {x}^{2} + \frac{d}{dx} x - \frac{ d }{dx} \frac{1}{x}$

$2x + 1 - ( \frac{ - 1}{ {x}^{2} } )$

$2x + 1 + \frac{1}{ {x}^{2} }$
