Reasonable Cheers, Severian Just like a question which has been given the 'official answer',but in fact there's more to think about. There're 2 evidences that Severian is right. 1,The original question is weird.'f(x) = 3x^2 + x^2 - 12X -4'=0 2,The original answer is also a little weird.'(3+/-sqrt13)/2'

use a better/more accurate title next time instead of 'geometry' i've done the picture, i use D,E instead of M,N, just the same

hmm,velocity and speed are often similar-they have the same numbers but AVERAGE velocity and AVERAGE speed ain't-they don't have the same numbers in most cases. i didn't know the true difference between velocity and speed before that.

agree

I often dream of someone shouting, then suddenly wake up, there's really someone shouting under my building, and the words that he/she is shouting is the same as the words he/she shouts in my dream.

WEIGHT approximately equals MASS*9.8, a balloon's weight is a VECTOR with positive NUMBER If you don't regard it as a vector, then it's a positive number

hmm you're not right 1, In High School Math, 0^0 and 0/0 are both undefined. 2, But in University, I am not sure. 3, Even if 0^0 is undefined, you cannot say 0^0 'EQUALS' undefined. It's a serious mistake.
