Answer:
D, C
Step-by-step explanation:
The only two rational expressions that have appropriate denominators are ...
1/(x² +6x) . . . contributes a factor of x to the denominator
(x+2)/(x² -36) . . . contributes a factor of (x -6) to the denominator
The proper order in the expression is ...
[tex]\displaystyle\dfrac{x+2}{x^2-36}-\dfrac{1}{x^2+6x}=\dfrac{x^2+x+6}{x(x-6)(x+6)}[/tex]
