# Solve and Matrix Question

## 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.

### RE: Solve and Matrix Question

The actual worksheet would be more useful than a picture of only part of it

### RE: Solve and Matrix Question

Is there any reason you need to do a symbolic solution?

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.

### RE: Solve and Matrix Question

(OP)
I would like to use the result of the solve for a later calculation, I know I could just copy and paste the result, but I would like to set it up so that I/or whomever comes after me, never has to do that again.

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?

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

Thank you all for your help, I am new to Mathcad, so this is something new I am learning, were it matlab, I could do it in a heartbeat, but alas Mathcad it is.  Again thank you for all your input.
