## Solve and Matrix Question

(OP)

I would like to use Mathcad to solve a second order polynomial; I would then like the assign that solution vector to a variable to be used again later for computation purposes. Any help would be appreciated.

You could use Given-Find or Root, but in both cases, you would need to limit the domain of the independent variable to get the root that you want.

You could just copy either of symbolic solutions and paste the solution into an assignment statement.

The solution returns two roots to the quadratic equation, only one of which is useful.

@Occupant, is there a way to specifically call the second entry in the Pcr_curv matrix?

## RE: Solve and Matrix Question

If you use root, your specification of the limits of the domain of Pcr_curv will dictate which solution is generated.

Yes, of course. It would be Pcr_curv[0,1 =
