- Homework Statement
- The question is as given in the image below and is part of a question bank for Calculus at high school (i.e. grade 12). The correct answer is supposed to be (C) two real roots.

- Relevant Equations
- None

When I look at the left hand side of the equation in above question then I can see that the highest degree of x would be 6 after the denominators are eliminated.

I know that a polynomial of degree n will have n roots, but this one is not a pure polynomial since there is also a trigonometric function.

I am confused on how to go about solving this problem. Any pointers would help. Probably something to do with functions chapter in Calculus.
