So I have the matrix

And it asks me to find the eigenvalues (as expressions in the parameter x)

So using λ=Lambda I got: λ^2-(2/5)λ-(1/5)x. How am I supposed to factor that to find the eigenvalues when x is there?

Thank you! I'm not sure why I didn't think to use the quadratic formula! I always forget to go back to basic principles lol
