Title: Completing the Square
Post by: SGVaibhav on March 06, 2010, 11:57:55 am

I don't understand completing the square at all :(

Please teach me completing the square to solve quadratic equations.

And also show me how to use completing the sqaure for integration   (this is very important)
(if something like  1  over x^2 ......)  then completing the square is used to change the form ( i also wanted to know that)
