Exercise
$\lim_{x\to3}\:\frac{x^2-\left(a+1\right)x+a}{x^3-a^3}$
Step-by-step Solution
Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x^2-(a+1)xa)/(x^3-a^3) as x approaches 3. Evaluate the limit \lim_{x\to3}\left(\frac{x^2-\left(a+1\right)x+a}{x^3-a^3}\right) by replacing all occurrences of x by 3. Calculate the power 3^3. Calculate the power 3^2. Multiply the single term -3 by each term of the polynomial \left(a+1\right).
