Homework Statement
Evaluate x-> 3 for (x^3-27)/(x-3) by as many methods as you can think of.
Homework Equations
The Attempt at a Solution
I could only think of one:
1) (x-3)(x^2+3x+9)/(x-3)= (x^2+3x+9)
3^2 + 3(3) + 9= 27
What other methods can I do? Is rationalizing the denominator an option, even if it is redundant? Thank you.
