-----------------------

Do not write two signs!

That means ________ is a root of the equation,

a zero of the function, and

an x-intercept on the graph!!

That also means that ________ is a factor of the polynomial.

And it means that ________ is also a factor, also know as

a reduced polynomial or

a depressed polynomial.

Getting zero in synthetic substitution is a big deal!!
