I compared mathplanet and mathisfun. Both sites are well structured, but math is fun is a very good name to make something funny, which is actually not fun to do, for most of us.
Beautiful thoughts, and yes only for believers.
Cool information about the human body and a good joke for men.
This is cool. That's why mathematicians are artists too.
let's do # 4
x^3 + 22x^2 121x = 0
Take "- x" out as gcf
- x (x^2 - 22x + 121) = 0
- x (x - 11)^2 = 0
So, -x = 0 which is x = 0 and (x - 11) = 0 which is x = 11
Hence x = 0, 11
cool joke, but gives some advice too.
I find this article on ezine article directory, may be help you to get how to solve equations with parenthesis.
Search for How-To-Solve-Complex-Equations-In-One-Variable in the directory.
I just joined too, and find it as a cool, informative site.
Math is cool too
