Thank you for the opportunity to help you with your question! I assume that you need to simplify the indicated expression. If not, let me know.

The least common multiple of s and t is LCM(s,t) = s*t. Multiplying both the (BIG) numerator and denominator by LCM(s,t) yields the following:

[t * t - s * s] / [s - t] = [t^2 - s^2] / [s - t] = [s - t] * [s + t] / [s - t] = s + t.

Please let me know if you need any clarification. I'm always happy to answer your questions.
