I am guessing the question is,       $\normalsize\color{blue}{   \frac{ \LARGE{4a+1}  }{\LARGE{a^2-4}}  -\frac{ \LARGE{3a+4}  }{\LARGE{a^2-4}} }$      right ?

jagr2713 · Answer

its a pretty long explanation

anonymous · Answer

subtract in the numerator, leave the denominator alone

anonymous · Answer

$$4a+1-(3a+4)=4a+1-3a-4=a-3$$

anonymous · Answer

the denominator stays the same, you get 
$$\frac{a-3}{a^2-4}$$
