Such as if I wanted to make a quadratic function, save it, and then later plug in any values of a,b,c in order to solve for
This was what I was thinking it would be:
fQ[a_,b_,c_]:=a x^2+b x+c ==0
Then I want to be able to call it and solve it with arbitrary values
I then get this:
Set::write: Tag Plus in 3+2 x+x^2 is Protected.
Solve::eqf: 0 is not a well-formed equation.
