The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Icould really use some with this question.
