add the fractions

Hey Christine,

Just like regular old fractions, we want to find a common denominator for these guys.

Let's multiply the 1/x by 1, but let's express 1 as x/x.

(x/x)(1/x) + 1/x^{2}

Multiplying that out, we get

x/x^{2} + 1/x^{2}

Now that we've found the common denominator, we can add the numerators and put them over one denominator.

So, our answer would be:

(x+1)/x^{2}
