Hello Shrutika,
By the expression that you have asked in your question it would be helpful for me if you would elaborate it because I am having difficulty in getting the question.
But if i may give a try , it's the question of differentiation and the question which i can interpret is x^7 + 3×2+6x+4(x+1) so it would turn out to 7x^6+0+6+4+0 which is equal to 7x^6+10.
Question : If $\left (x+\frac{1}{x}\right )=5$, find the value of $\frac{6x}{x^{2}+x+1}$.
Option 1: 3
Option 2: 2
Option 3: 1
Option 4: 0
