Answer:

\frac{2}{ x^{2} }  +  \frac{4}{ x^{2} } =  \frac{2+4}{ x^{2}}=  \frac{6}{ x^{2} }  

Step-by-step explanation:

When we add two expression in fraction we take Least common multiple of two expression  in the denominator

Here we have expression  

Now, we write a common denominator

rewrite the expression

Now, we combine the numerator 2+4 is equal to 6

So, we will get   = \frac{2}{x^{2}}+ \frac{4}{x^{2}} =\frac{6}{x^{2} }

Hope this helps!
