$\lim_{x\to-3}\left(\frac{x\left(x^2-9\right)}{x+3}\right)$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(-3)lim((x^3-9x)/(x+3)). Factor the polynomial x^3-9x by it's greatest common factor (GCF): x. The difference of the squares of two terms, divided by the sum of the same terms, is equal to the difference of the terms. In other words: \displaystyle\frac{a^2-b^2}{a+b}=a-b.. Evaluate the limit \lim_{x\to-3}\left(x\left(x-3\right)\right) by replacing all occurrences of x by -3. Subtract the values -3 and -3.
