Re: Integral by u Sub.

Alternatively, check your work after each test, and make a conscious effort to concentrate more ...

Re: STEM fields vs. Humanites

I think in trying to evaluate which is harder, you must determine which requires more intelligence. And, going off of what modularblues was saying, I think therein lies the main problem in trying to evaluate this, because people involved in STEM fields think differently from people who are in humani...

Re: Completeing the Square

If you did set it equal to zero, you wouldn't need to complete the square in the first place:

2x-x^2 = 0
x(2-x) = 0

x = 2, 0

And in other cases, if it's set to y, like jwoo said, the -1 would get applied to the y as well.
