Hi,

I'm in Grade Twelve Academic Math and I need to know how to find the minimum of any given problem.

PLEASE PUT DOWN STEPS to finding the minimum, not just writing a question then jumping to the answer.

I would really appreciate the help.

I don't think so, I'm not great at math yet I'm in academic math(not basic).

well, there are several ways of doing this. the two most prominent ways are to: (1) complete the square, or (2) use the vertex formula.

note that only quadratics where the coefficient of x^2 is positive have a minimum value, and it occurs at their vertex. post a specific question if you want to see these methods demonstrated - Oct 16th 2007, 10:50 AMSnipedYou
It should be $\displaystyle (\frac{-b}{2a},$ the value of x put into the original equation) right?
