The Quadratic Formula Explained says:

So, while factoring may not always be successful, the Quadratic Formula canalwaysfind the solution.

I'm trying to use the Quadratic Formula to solve $\displaystyle 1.26x^2-186.56x+34041.94=0$ but my $\displaystyle 4ac$ is much bigger than my $\displaystyle b^2$ so everything under the radical evaulates to a negative number. How can I solve this?
