Is there a way to display something like the quadratic equation, i.e. with a
numerator and demonator on a plot?
I think there is a way to create the equation in Latex, but wasn't sure if this
format would translate to plotting.
\begin{equation}
x = \frac{b +/- sqrt(b^2 - 4*a*c)}{2*a}
\end{equation}
My searched turned up the following:

Unfortunately, it does not address equations with numerators and demomenators.
Here is a guess (but this fails):
### Change spacing to allow for multiline title
par(oma=c(2, 0, 4, 0))
### Some greek letters
mu <- 0
alpha <- 1
beta <- 2
delta <- 3
lambda <- 4
### Some graph or other
plot(1:10,1:10)
mtext(expression(bold("Meaningless Title")),
line=3.5,cex=1.15)
mtext(bquote(x == \frac{b +/- sqrt(b^2 - 4*a*c)}{2*a}, line=2.25,cex=1.15)
Thanks again for any and all help.
