To combine the expressions 1/(2x^2) and -5/(2x^2), you need to find a common denominator. In this case, the common denominator is 2x^2.

To do this, multiply the numerator and denominator of the first fraction, 1/(2x^2), by 5 to get 5/(10x^2).

Now, you can combine the two fractions by subtracting the second fraction, -5/(2x^2), from the first fraction, 5/(10x^2).

Subtracting the fractions gives you (5 - (-5))/(10x^2), which simplifies to 10/(10x^2).

Finally, you can simplify further by canceling out the common factor of 10 in the numerator and denominator, resulting in 1/x^2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
