I'm not that good with using the equation editor, so I scanned my work.

I'm stuck on the last part where i'm trying to factor the equation to find a solution for [tex]\lambda[/tex], I cant seem to find a solution that would make the equation zero, which is what i need in order to do the long division to factor that equation.
