If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.

When I’m doing algebra, I generally just add 6 to everything (it worked once, I’m hopeful it’ll do so again).

How did you figure it out?

Graphing the function and seeing where it crosses the axis. You can tell from the coefficients that all real roots are negative. The roots are irrational, so the best approach, unless you are doing algebraic number theory, is to use approximations.
