First separate it into three separate factors and then find the common denominator. Multiply the common denominator to the top and bottom. Combine like terms and set it as a system. Then with a calculator plug it the same way as if you're plugging in a matrix. The answer from that should be your equation.
The trickiest part of this problem is probably when you multiply the common denominator to the top and bottom because C only needs one and it's (x-1). Also when you combine like terms, it can be easy to make a silly mistake there.
