Reallyman said:I haven't been in college for 8 years and my first math class is Math 140. I understand the concepts but simplifying the equation to find the limit is killing me. Does anyone no the name of this formula and what to study to catch up? thanks
There is no particular name for "re-arranging formulas". The expression given:
\(\displaystyle a^3 \ + \ a^2b \ + \ ab^2 \ + \ b^3\)
can become
\(\displaystyle = \ a^2\cdot (a \ + \ b) \ + \ b^2 \cdot (a \ + \ b)\)
\(\displaystyle = \ (a \ + \ b)\cdot (a^2 \ + \ b^2)\)
Thanks this one homework problem is kicking my butt. Didn't realize I could break it down further. I'll try that. I would post the whole problem but its full of Delta X's. Anyway i want to give it a go by myself anyway so to retain the material, first. Thanks for the direction, and i like your quote!

As you see - that is not my quote. Some people will claim (including me) that Neumann was the greatest mathematician of twentieth century (now if he did not understand things.......who am I to claim understanding????)
