How to solve this step by step?
Limit[(x^3-13x^2+51x-63)/(x^3-4x^2-3x+18),x->3]
Thank you guys so much that helped me alot :D
Paste that in Wolfram|Alpha and click step-by-step link. Here is what you get:
Sometimes you can see it directly with commands such as simplify/factor/apart
Now it is easy to see the value when x "approaches" 3 :)
What do you mean when you say "Step by Step"? It's just
Limit[(x^3 - 13 x^2 + 51 x - 63)/(x^3 - 4 x^2 - 3 x + 18), x -> 3] (* Out[7]= -(4/5) *)
If you like a mathematical explanation, you should consider asking this on math.stackexchange.com
What i ment by "step by step" is how did you evaluate the limit to end up with this answer
