# Adding and Subtracting Rational Expressions (Part 2)

1. 1
Simplify and state any restrictions. $$\frac{3}{x-1}+\frac{4}{x-1}$$
2. 2
Simplify and state any restrictions. $$\frac{5}{x-3}+\frac{1}{x+2}$$
3. 3
Simplify and state any restrictions. $$\frac{x}{x+5}+\frac{2x}{x-3}$$
4. 4
Simplify and state any restrictions. $$\frac{4}{x-5}-\frac{6x}{6x-30}$$
5. 5
Simplify and state any restrictions. $$\frac{3x+1}{3(x-2)}+\frac{x}{2x-4}$$
6. 6
Simplify and state any restrictions. $$\frac{4}{x^2+x-6}+\frac{2}{x-2}$$
7. 7

9. 9
Simplify and state any restrictions. $$\frac{3x}{x^2+5x-14}-\frac{2}{x+7}$$
10. 10
Simplify and state any restrictions. $$\frac{2x}{x^2+4x+3}-\frac{4}{x+3}$$
11. 11
Simplify and state any restrictions. $$\frac{x-2}{x^2+4x-12}-\frac{x+3}{x^2+7x+12}$$  good test question!
12. 12
Simplify and state any restrictions. $$\frac{m+6}{m^2+9m+18}-\frac{m-3}{m^2-2m-3}$$
13. 13
Simplify and state any restrictions. $$\frac{m^2+m-6}{m^2-3m+2}-\frac{m^2+3m+2}{m^2-m-2}$$
14. 14
Simplify and state any restrictions. $$\frac{2}{2m^2+3m-2}-\frac{3}{3m^2+4m-4}$$

Simplify and state any restrictions. $$\frac{1}{1+\cfrac{1}{1+\cfrac{1}{x}}}$$  Need to simplify using both adding / subtracting and multiplying / dividing rational expressions. Good test question!
$$e=mc^2$$
