\/ 2*x  + 3

\frac{\sqrt{4 x} + 1}{\sqrt{2 x} + 3}

(sqrt(4*x) + 1)/(sqrt(2*x) + 3)

Detail solution

Apply the quotient rule, which is:

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

$f{\left(x \right)} = 2 \sqrt{x} + 1$ and $g{\left(x \right)} = \sqrt{2} \sqrt{x} + 3$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. Differentiate $2 \sqrt{x} + 1$ term by term:
  1. The derivative of the constant $1$ 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: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
    So, the result is: $\frac{1}{\sqrt{x}}$
  The result is: $\frac{1}{\sqrt{x}}$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Differentiate $\sqrt{2} \sqrt{x} + 3$ term by term:
  1. The derivative of the constant $3$ 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: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
    So, the result is: $\frac{\sqrt{2}}{2 \sqrt{x}}$
  The result is: $\frac{\sqrt{2}}{2 \sqrt{x}}$
Now plug in to the quotient rule:

$\frac{- \frac{\sqrt{2} \left(2 \sqrt{x} + 1\right)}{2 \sqrt{x}} + \frac{\sqrt{2} \sqrt{x} + 3}{\sqrt{x}}}{\left(\sqrt{2} \sqrt{x} + 3\right)^{2}}$
Now simplify:

$\frac{6 - \sqrt{2}}{4 x^{\frac{3}{2}} + 18 \sqrt{x} + 12 \sqrt{2} x}$

The answer is:

\frac{6 - \sqrt{2}}{4 x^{\frac{3}{2}} + 18 \sqrt{x} + 12 \sqrt{2} x}
