\frac{d}{dx}\left(\frac{a+bx}{a-b\cdot x}\right)

Derive the function (a+bx)/(abx*-1) with respect to x

Answer

$\frac{b\left(x\cdot b+a\right)+b\left(a-x\cdot b\right)}{\left(a-x\cdot b\right)^2}$

Step-by-step explanation

Problem

$\frac{d}{dx}\left(\frac{a+bx}{a-b\cdot x}\right)$
1

Applying the quotient rule which states that if $f(x)$ and $g(x)$ are functions and $h(x)$ is the function defined by ${\displaystyle h(x) = \frac{f(x)}{g(x)}}$, where ${g(x) \neq 0}$, then ${\displaystyle h'(x) = \frac{f'(x) \cdot g(x) - g'(x) \cdot f(x)}{g(x)^2}}$

$\frac{\left(a-x\cdot b\right)\frac{d}{dx}\left(x\cdot b+a\right)-\left(x\cdot b+a\right)\frac{d}{dx}\left(a-x\cdot b\right)}{\left(a-x\cdot b\right)^2}$
