Transform

Detail solution

Apply the quotient rule, which is:

$\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$

$f{\left(x \right)} = 5 x^{2} - 3 x$ and $g{\left(x \right)} = 3 x - 8$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. Differentiate $5 x^{2} - 3 x$ term by term:
  1. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $x$ goes to $1$
    So, the result is: $-3$
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $x^{2}$ goes to $2 x$
    So, the result is: $10 x$
  The result is: $10 x - 3$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Differentiate $3 x - 8$ term by term:
  1. The derivative of the constant $-8$ is zero.
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $x$ goes to $1$
    So, the result is: $3$
  The result is: $3$
Now plug in to the quotient rule:

$\frac{- 15 x^{2} + 9 x + \left(3 x - 8\right) \left(10 x - 3\right)}{\left(3 x - 8\right)^{2}}$
Now simplify:

$\frac{15 x^{2} - 80 x + 24}{9 x^{2} - 48 x + 64}$

The answer is:

$\frac{15 x^{2} - 80 x + 24}{9 x^{2} - 48 x + 64}$
