Youre better off than my Professor as this would save me from further embarrassment of my ignorance against these bloody numbers. Worth the subscribe! Kudos!

At 4:50 you say that the last term of the polynomial (which is "-5") has no coefficient. That is WRONG: "-5" is itself the coefficient, it is the "x" next to it that has a Degree of "0", making it equal to 1, therefore being disconsidered.
