0 = -250*(sqrt(x^2+1)-0.8)^2 + 98.1*x + 59.05

## Homework Equations

## The Attempt at a Solution

I can't figure out how to solve this equation! After expanding the squared term, I still end up with a sqrt(x^2+1) and I can't figure out how to perform a substitution or something to make it a nice clean quadratic.
