Answer: [tex]\frac{2}{k+2}[/tex]
Explanation:
Firstly, we will split the denominator [tex]k^{2} -4 =(k-2)(k+2)[/tex] by the formula of ([tex]a^{2} -b^{2}[/tex]) = (a-b)(a+b)
then, the given terms [tex]\frac{4k+2}{k^{2}-4} * \frac{k-2}{2k+1}[/tex]
will become [tex]\frac{4k+2}{(k-2)(k+2)} *\frac{k-2}{2k+1}[/tex]
now, cancel the common factor that is k-2 we get
[tex]\frac{4k+2}{(k+2)(2k+1)}[/tex]
Now taking 2 as common from 4k+2 we will get 2(2k+1)
we will get [tex]\frac{2(2k+1)}{(k+2)(2k+1)}[/tex] common factor will get cancelled which is 2k+1
Hence, we will finally get [tex]\frac{2}{k+2}[/tex]
