The given expression is 
We need to determine the expression as an equivalent algebraic expression involving only x.
The expression
has to be expressed as an algebraic expression in x.
Thus, we have;

Using the identity
in the above expression, we get;

Simplifying, we get;
![\cos \left(2 \cos ^{-1} x\right)=2[cos(cos^{-1}x)]^2-1](https://tex.z-dn.net/?f=%5Ccos%20%5Cleft%282%20%5Ccos%20%5E%7B-1%7D%20x%5Cright%29%3D2%5Bcos%28cos%5E%7B-1%7Dx%29%5D%5E2-1)


Hence, the expression
can be written as
