Hi, 

I'm starting in mathcad and can´t solve a simple problem. I have a function 

f(x) = 6.08 - 5.11*x + 1.04*X^2 and I have a matrix with many values of f(x). I would like to create a matrix whose rows are root of equation f(x). I will attached the matrix of f(x).

 

Thank you

Not sure what you are asking. f(x) is a quadratic so has exactly 2 roots. What is you table?

Hi,

I'm just guessing ... that 7_mathcad.TXT file contains f(x) values in its second column and OP wants to get x values related to them.
