To simplify (2x-10)/(3x - 21), you can factor out a common factor of 2 from the numerator and 3 from the denominator, resulting in (2(x-5))/(3(x - 7)). The restrictions for this expression are that x cannot equal 7, as it would result in division by zero.

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.
