I am doing a calculus course where my textbook is factorizing one step further than most online step-by-step calculators I have found without really explaining how. Now I am working on factorizing a cubic function, and I am stuck at one part. The book says:

\(\displaystyle 3x^2+8x-3=3\left(x-\frac{1}{3}\right)\left(x+3\right)\)

I get that you take out the GCF but I can't figure out the other steps behind this. Hopefully someone here can help.
