Problem:

Determine
$\lim_{x\to -3}\frac{x^3+27}{x+3}.$

Answer:

27

Solution:

Usually when <Sign in to see all the formulas> and <Sign in to see all the formulas> the limit <Sign in to see all the formulas> does not exist. However, if we can find an $x+3$ in the numerator to cancel the $x+3$ in the denominator the function limit might exist.
