Is there a way for the solve app to use exact figures?

[Lord_Spooglypuff]

Hi there.

I am trying to solve this equation:

a^2+b^2+c^2+6=a given that b=6 and c=31.

I'm particularly having trouble trying to get the given parts of that equation to work

I know how to do this via the solve app, but I can't get exact figures with the app, and it doesn't play nice with non-linear equations.

So is there a different way solve that equation and still get exact figures?
