Question

lim(x^3-27)/(x-3)
xarrow>3

Answer 1

\[\lim_{x \rightarrow 3}\frac{x^3-27 }{ x-3}\]

Answer 2

The numerator is a difference of cubes; it can be factored. After factoring you will be able to cancel the common (x-3) factors in the numerator and denominator, remembering that x cannot equal 3. Then get your limit as usual....
