Hi all,
I have 2 columns:
X = X1, X2, X3,X4...
Y = Y1, Y2, Y3, Y4...
Relationship between Y and X is quadratic equation: Y = AX^2 + BX + C
How can i obtain A, B, C by Excel?
Thanks for help!

I prefer to use the LINEST() function. =LINEST(known_y's, known_x's^{1,2}) See help for the LINEST function for more details, and remember that LINEST is an array function, so it must be confirmed with ctrl-shift-enter.
Thanks for help!
