Final Simplification of Complex Rational Expressions

A laboratory technician is simplifying a formula for chemical concentration: 2x+64x64x236\frac{\frac{2}{x+6}}{\frac{4}{x-6}-\frac{4}{x^2-36}}. After clearing the inner fractions, the technician arrives at the intermediate form: 2(x6)4x+20\frac{2(x-6)}{4x+20}. What is the final, fully simplified form of this expression?
