Those are a couple of my favorite sites for online tutorials, but there are a few other good ones also, such as ask dr. math and amby.com.
To find tutorials on any subject just put subject tutorial in your search window. For example when I put quadratic formula tutorial in my search window here are a few of the sites that come up:
http://www.purplemath.com/modules/solvquad.htm
http://www.wtamu.edu/academic/anns/mps/math/mathlab/col_algebra/col_alg_tut17_quad.htm
http://www.gomath.com/members/test/tutorial/section3/p1.html
When you do this you'll turn up a variety of tutorials on various levels and with varying qualities of explanations and graphics. Pick the one that suits you best. The above three links are not the first three that came up, but they are three that I liked best.
