Find the degree of the polynomial `1/(sqrt(4x+1)){((1+sqrt(4x+1))/2)^7-((1+sqrt(4x+1))/2)^7}`

Explanation

To find the degree of the polynomial given by

\[ L = \frac{1}{\sqrt{4x + 1}} \left( \left( \frac{1 + \sqrt{4x + 1}}{2} \right)^7 - \left( \frac{1 - \sqrt{4x + 1}}{2} \right)^7 \right), \]

we will follow these steps:
